Isopropylphenidate (IPPH) 25 MG Pellets

Buy Isopropylphenidate (IPPH) 25 MG Pellets Research Chemical Online – USA, Europe & Worldwide

Welcome to RChems EU, a globally trusted supplier of high-purity research chemicals serving academic, pharmaceutical, and forensic laboratories across five continents. Our Isopropylphenidate (IPPH) 25 MG Pellets offer researchers a standardized, analytically verified tool for exploring the pharmacology of phenidate-class compounds.

Isopropylphenidate (IPPH) is a synthetic phenidate analog and a derivative of methylphenidate (Ritalin), featuring an isopropyl ester group instead of the methyl ester found in the parent compound. This structural modification alters the compound’s lipophilicity, metabolic stability, and transporter binding kinetics. As a dopamine reuptake inhibitor (DRI) with selectivity for the dopamine transporter (DAT) over the norepinephrine transporter (NET), IPPH serves as a valuable research tool for studying structure-activity relationships (SAR) within the phenidate family, as well as dopaminergic signaling, attention mechanisms, and locomotor activity.

Purity & Testing

At RChems EU, we understand that research reproducibility begins with compound integrity. Every batch of 99% pure Isopropylphenidate (IPPH) 25 mg pellets undergoes a comprehensive, multi-tiered analytical workflow before release:

1. High-Performance Liquid Chromatography (HPLC-DAD): Quantifies purity against a certified reference standard at dual wavelengths (210 nm and 254 nm). Acceptance criterion: ≥99.0% main peak area. All impurities ≥0.05% are reported with retention times.
2. Liquid Chromatography-Mass Spectrometry (LC-MS/MS): Confirms molecular ion [M+H]⁺ at m/z 262.2 and characteristic fragmentation pattern (loss of isopropyl group, cleavage of the ester bond). Rules out isobaric contaminants and synthetic byproducts.
3. Nuclear Magnetic Resonance (¹H and ¹³C NMR): Unambiguously confirms structural identity, including the isopropyl ester group and the piperidine ring stereochemistry. Verifies absence of unexpected synthetic intermediates or regioisomers.
4. High-Resolution Mass Spectrometry (HRMS-TOF): Provides exact mass measurement (calculated for C₁₆H₂₃NO₂: 261.1729; observed: 261.1727 ± 2 ppm) to rule out isobaric contaminants and confirm elemental composition.
5. Karl Fischer Coulometry: Ensures moisture content below 0.5%, critical for long-term pellet stability and preventing hydrolytic degradation of the ester group.
6. Content Uniformity Testing (USP <905>): Random sampling of 10 pellets from each batch ensures each individual pellet contains 25mg ± 10% of active ingredient, with relative standard deviation (RSD) <6%.
7. Residual Solvent Analysis (GC-FID): Quantifies residual organic solvents from synthesis per ICH Q3C guidelines.

Only batches that pass all seven checkpoints are released for distribution. This rigorous approach means when you buy Isopropylphenidate (IPPH) for research from RChems EU, you eliminate batch-to-batch variability—a primary cause of non-reproducible results in dopamine transporter pharmacology and forensic toxicology.

FAQ Section

Q1: What is Isopropylphenidate (IPPH) 25 mg used for in research?
A: Isopropylphenidate (IPPH) is a phenidate analog and a dopamine reuptake inhibitor (DRI) with selectivity for the dopamine transporter (DAT) over the norepinephrine transporter (NET). Typical research applications include DAT binding assays (radioligand displacement), transporter selectivity studies comparing IPPH to methylphenidate and ethylphenidate, structure-activity relationship (SAR) research on ester chain length, analytical method development for forensic toxicology (LC-MS/MS, GC-MS), and metabolic stability profiling using human liver microsomes and plasma esterases. It is not for human or animal consumption.

Q2: Is Isopropylphenidate (IPPH) legal to buy for research?
A: Legality varies significantly by country and jurisdiction. In the USA, IPPH is not currently scheduled at the federal level but may be subject to the Federal Analogue Act if intended for human consumption—legitimate in-vitro research by licensed institutions may be permissible. The UK Psychoactive Substances Act, German NpSG, Canadian CDSA, and Australian poisons standards may regulate this compound as a controlled substance analogue. You are solely responsible for verifying your local laws and obtaining any required licenses or permits before ordering. RChems EU will not ship to jurisdictions with outright bans. Contact our compliance team with your institutional affiliation for a jurisdiction-specific assessment.

Q3: How discreet is your shipping packaging?
A: Extremely discreet. The outer package is a plain, unmarked box or padded envelope with no branding, no chemical names, no hazard warnings, and no logos. The return address is a generic “Fulfillment Department” or “Logistics Center” with no mention of RChems EU or “research chemicals.” The customs declaration lists only generic, non-suspicious terms such as “laboratory consumables,” “non-hazardous solid reference material,” or “in vitro diagnostic reagents (non-human).” Inside, the pellets are sealed in an opaque, vacuum-sealed mylar pouch with no external labeling. Even the courier tracking page shows only a nondescript sender name. We have maintained a 99.7% successful delivery rate to research institutions globally over the past 24 months.

Q4: What is the exact purity level, and how is it tested?
A: Minimum 99% pure Isopropylphenidate as determined by HPLC-DAD at dual wavelengths (210 nm and 254 nm). Each batch’s Certificate of Analysis includes the exact purity percentage (typically 99.2–99.6%), representative chromatograms, LC-MS/MS total ion chromatogram, ¹H and ¹³C NMR spectrum summaries, residual solvent profile, heavy metals analysis, and moisture content. We use orthogonal analytical methods (HPLC + LC-MS + NMR + HRMS) to confirm both identity and purity. No batch with any single unspecified impurity exceeding 0.2% is ever released for sale.

Q5: How should I store Isopropylphenidate (IPPH) 25 mg pellets after opening?
A: Store in the original sealed mylar pouch or transfer immediately to a tight, amber glass vial with a desiccant packet (silica gel, 3–5 grams). Keep at controlled room temperature (15–25°C / 59–77°F), away from direct sunlight, heat sources, open flames, oxidizing agents, and humidity exceeding 60%. Do not refrigerate or freeze, as condensation upon opening may degrade pellet integrity and accelerate hydrolytic degradation of the ester group. Under proper storage conditions, chemical stability remains ≥98% for 24 months from the date of manufacture. Always allow the sealed container to reach room temperature before opening to minimize moisture uptake.

Q6: What quantity options are available?
A: Isopropylphenidate (IPPH) 25 MG Pellets are available in four quantity options: 25 pellets, 50 pellets, 100 pellets, or 250 pellets. This flexibility allows researchers to order appropriate amounts for pilot studies, full-scale experiments, or long-term research programs. Volume discounts apply to larger quantities.

Q7: Can I receive a Certificate of Analysis before placing an order?
A: Absolutely. Contact our scientific support team with the product name (Isopropylphenidate (IPPH) 25 MG Pellets), your institutional affiliation, and intended research application. We will provide a representative CoA from the current or most recent production batch, including HPLC purity percentage, impurity profile, chromatograms, and NMR summary. Full, lot-specific CoAs are included inside every shipment. For bulk or custom orders, we can provide pre-production reference data.

Q8: Are the pellets scored or designed for division?
A: No. The pellets are manufactured as homogeneous, whole-unit analytical standards. They are not scored and are not designed for splitting, cutting, or mechanical division. Crushing, cutting, or otherwise manipulating pellets will compromise dose uniformity and is not recommended for accurate, reproducible research. For studies requiring multiple concentration points, dissolve entire pellets in an appropriate solvent (e.g., DMSO for 10–20 mM stock solutions, ethanol for working dilutions) and perform serial volumetric dilutions using Class A volumetric glassware.

Q9: How does IPPH differ from methylphenidate?
A: Isopropylphenidate (IPPH) differs from methylphenidate (Ritalin) in the ester group: IPPH has an isopropyl ester, while methylphenidate has a methyl ester. This structural modification increases lipophilicity and alters metabolic stability—IPPH is more resistant to esterase-mediated hydrolysis than methylphenidate, potentially resulting in different pharmacokinetic profiles. Both compounds act as dopamine reuptake inhibitors, but the isopropyl group may affect transporter binding kinetics and selectivity for DAT versus NET, making IPPH a valuable SAR research tool.

Q10: Can I request a custom dosage or larger quantity?
A: Yes. For research institutions requiring custom dosing formats (e.g., 10mg, 15mg, 30mg, 50mg pellets) or larger batch quantities (500+ pellets or 1000+ pellets), please contact our institutional sales team. We offer custom synthesis and custom pellet compression services with the same ≥99% purity guarantee and full analytical testing (HPLC, LC-MS, NMR, HRMS). Minimum order quantities vary by dosage. Contact us for a quotation and to discuss your specific research requirements.

Q11: What solvents are recommended for dissolving Isopropylphenidate pellets?
A: Isopropylphenidate is freely soluble in DMSO (>50 mg/mL) and ethanol (>40 mg/mL). It is sparingly soluble in water (<0.5 mg/mL) and propylene glycol. For transporter binding assays, prepare a 10 mM stock solution in DMSO, then dilute in assay buffer (final DMSO concentration <0.1% to avoid cell toxicity). For analytical standards, use methanol or acetonitrile. Avoid prolonged exposure to light and heat after dissolution. Solutions in DMSO or ethanol are stable for up to 3 months when stored at -20°C in amber glass vials.
