4-HO-MiPT fumarate

Buy 4-HO-MiPT Fumarate Research Chemical Online – USA, Europe & Worldwide

Among the family of 4-substituted tryptamines, 4-HO-MiPT fumarate (4-hydroxy-N-methyl-N-isopropyltryptamine fumarate) occupies a distinctive position as a structural analog of both psilocin (4-HO-DMT) and the 5-methoxylated tryptamine 5-MeO-MiPT. The 4-hydroxy group makes this compound a member of the 4-hydroxytryptamine family, which includes the well-known research chemical psilocin. However, the N-alkyl substitution pattern—one methyl group and one branched isopropyl group—sets 4-HO-MiPT apart from the dimethyl substitution of psilocin and the diisopropyl substitution of other analogs.

This combination of a 4-hydroxy group with an asymmetric, branched N-alkyl pattern (methyl + isopropyl) creates a unique pharmacological profile. The branched isopropyl group introduces steric bulk that can significantly influence receptor binding kinetics, selectivity, and intrinsic activity compared to linear-chain analogs. For researchers investigating structure-activity relationships within the tryptamine family, 4-HO-MiPT fumarate offers a valuable tool for understanding how branching at the N-alkyl position impacts serotonin receptor interactions. When you buy 4-HO-MiPT fumarate from RChems EU, you acquire a high-purity research compound manufactured under strict quality controls. Our 99% pure 4-HO-MiPT fumarate is intended exclusively for laboratory research—not for human or animal consumption—enabling precise, reproducible experiments in receptor pharmacology, neurochemistry, and SAR studies.

Purity & Testing

Reproducibility in serotonin receptor research depends critically on compound purity. Impurities—particularly other 4-hydroxylated tryptamine isomers, N-desalkyl byproducts, or oxidative degradation products (the 4-hydroxy group can be susceptible to oxidation)—can produce false-positive signals in radioligand binding assays or confound functional response curves. That is why 99% pure 4-HO-MiPT fumarate from RChems EU is subjected to a multi-laboratory quality control workflow:

1. High-Performance Liquid Chromatography (HPLC-DAD): Quantitative analysis at 220 nm, 254 nm, and 280 nm (indole ring absorption). Special attention is given to detecting oxidative degradation products. Minimum acceptance criterion: ≥99.0% peak area purity.
2. Liquid Chromatography-Mass Spectrometry (LC-MS): Confirms molecular ion [M+H]⁺ = 233.2 for the freebase and detects trace-level organic impurities down to 0.05%, including potential oxidation products.
3. Nuclear Magnetic Resonance (NMR): Both proton (¹H) and carbon-13 (¹³C) NMR verify the correct indole ring system, 4-hydroxy substitution (characteristic downfield OH proton exchangeable with D₂O), and mixed methyl/isopropyl N-substitution pattern (methyl singlet, isopropyl methine and methyl splitting). Any spectral deviation—particularly signals indicative of degradation or isopropyl group misassignment—triggers batch rejection.
4. Residual Solvent Analysis (GC-MS): Ensures compliance with ICH limits for Class 2 and Class 3 solvents.
5. Heavy Metal Testing (ICP-MS): Confirms levels below 20 ppm for lead, arsenic, cadmium, and mercury.

Each batch is assigned a unique lot number, and a Certificate of Analysis (COA) is available upon request. This rigorous testing ensures that when you buy 4-HO-MiPT fumarate for research, you receive a compound that performs consistently from order to order.

6. Can you ship 4-HO-MiPT fumarate to my country (USA, UK, Germany, Australia, Canada)?

RChems EU ships 4-HO-MiPT fumarate worldwide, including the USA, Canada, United Kingdom, Germany, France, Italy, Spain, Netherlands, Switzerland, Norway, Australia, and New Zealand. However, due to varying legal statuses of tryptamine derivatives, we strongly recommend contacting our support team before ordering if you are located in Germany, Sweden, Finland, or any country with broad analogue legislation. For countries with strict import controls (e.g., Japan, Singapore, South Korea), we do not currently ship 4-HO-MiPT fumarate.

7. How should I store 4-HO-MiPT fumarate after delivery?

Store 4-HO-MiPT fumarate in a tightly sealed, amber glass vial under refrigeration (4°C) to minimize oxidative degradation of the 4-hydroxy group. For short-term use (≤2 weeks), room temperature (20–25°C) in a desiccator under inert atmosphere (argon or nitrogen) may be acceptable. Always allow the sealed container to reach room temperature before opening to prevent condensation. Avoid prolonged exposure to air, light, and heat.

8. What is the difference between 4-HO-MiPT and psilocin (4-HO-DMT)?

The key structural difference lies in the N-alkyl substitution pattern:

• Psilocin (4-HO-DMT) has two methyl groups on the terminal amine (N,N-dimethyl) – small, linear
• 4-HO-MiPT has one methyl and one isopropyl group (N-methyl-N-isopropyl) – one linear, one branched

In serotonin receptor research, the introduction of a branched isopropyl group creates significant steric bulk that can alter receptor binding affinity, selectivity for 5-HT2A vs. 5-HT1A vs. 5-HT2C, metabolic stability, and intrinsic efficacy. Comparing 4-HO-MiPT with psilocin allows researchers to systematically map the impact of N-alkyl branching on 4-hydroxytryptamine pharmacology.

9. What is the difference between 4-HO-MiPT and 4-HO-MPT?

The difference lies in the N-alkyl chain structure:

• 4-HO-MPT has a methyl and a linear propyl group (CH₂CH₂CH₃)
• 4-HO-MiPT has a methyl and a branched isopropyl group (CH(CH₃)₂)

Both have the same molecular formula (C₁₄H₂₀N₂O) but are structural isomers. Comparing these two compounds allows researchers to investigate how chain branching (isopropyl) vs. linear chain (propyl) of the same carbon length affects serotonin receptor binding, selectivity, and functional activity. This is a classic structure-activity relationship (SAR) study comparing linear vs. branched alkyl isomers.

10. What is the difference between 4-HO-MiPT and 4-AcO-MiPT?

4-HO-MiPT has a hydroxy group (-OH) at the 4-position, while 4-AcO-MiPT has an acetoxy group (-OCOCH₃) at the same position. In biological research models, the acetoxy group is considered a prodrug moiety that is hydrolyzed by esterases to yield the active 4-hydroxy compound. Comparing 4-HO-MiPT with 4-AcO-MiPT allows researchers to study:

• • Hydrolysis rates in various in vitro systems (plasma, liver microsomes, brain tissue)

• Stability differences between the two forms
• Metabolic activation pathways for acetoxy tryptamines

11. Do you offer a reshipment policy if customs seizes my package?

Yes. RChems EU offers a one-time reshipment policy for confirmed customs seizures in most countries, provided that the original shipping address is valid and the buyer did not violate known local laws. Crypto payments qualify for the full reshipment guarantee. Terms and conditions apply—please contact customer support for details.
