⚠️ Strictly for laboratory research use only. Not for human or animal consumption.

Etizolam 1mg blotters are utilized in a range of non-clinical, pre-clinical, and basic science research applications where pre-dosed formats offer advantages over powdered chemicals. Typical areas of investigation include:

  • GABA-A Receptor Binding Assays: After dissolution of the blotter in appropriate solvent (ethanol or DMSO), researchers can evaluate affinity (Ki) for the benzodiazepine binding site on GABA-A receptor subtypes (α1β2γ2, α2β3γ2, α3β3γ2, α5β3γ2) using radioligand displacement (e.g., [³H]flumazenil or [³H]Ro15-1788) in rat brain homogenates or transfected cell lines.
  • Positive Allosteric Modulation Functional Studies: Measuring GABA-induced chloride influx or electrophysiological recordings (patch-clamp) to assess the potency and efficacy of Etizolam as a positive allosteric modulator across different GABA-A receptor subunit combinations.
  • Thienodiazepine vs. Benzodiazepine SAR Investigations: Systematically comparing Etizolam (thiophene ring) with classical benzodiazepines such as alprazolam or diazepam (benzene ring) to map the impact of heterocyclic ring substitution on receptor subtype selectivity, intrinsic efficacy, and metabolic stability.
  • Blotter-Based Dosing Studies: The pre-dosed 1mg blotter format enables consistent, repeatable dosing across multiple experimental replicates, particularly useful for studies requiring solid-phase extraction or controlled release from the blotter matrix.
  • Metabolic Stability Research: Evaluating phase I and phase II metabolism using hepatic microsomes or S9 fractions with LC-MS/MS quantification after extraction from the blotter matrix.
  • Analytical Reference Standard Preparation: Blotters can be extracted to prepare calibrated solutions for forensic toxicology, wastewater analysis, or novel psychoactive substance (NPS) screening methods.
  • In Vitro Neurotoxicity Screening: Assessing cytotoxicity, mitochondrial function, and oxidative stress markers in neuronal cell cultures (e.g., SH-SY5Y, primary cortical neurons).

Researchers are encouraged to consult peer-reviewed literature (e.g., Journal of Medicinal Chemistry, Neuropharmacology, European Journal of Pharmacology, Psychopharmacology) for established in vitro protocols. RChems EU does not provide research protocols but guarantees the compound’s structural integrity and purity for such applications.

Purity & Testing

Reproducibility in GABA-A receptor and neuropharmacology research depends critically on compound purity. The active ingredient on each Etizolam 1mg blotter is subjected to rigorous independent testing before blotter preparation. Impurities—particularly other thienodiazepine isomers, synthetic intermediates, or degradation products—can produce false-positive signals in receptor binding assays or confound functional readouts. That is why 99% pure Etizolam is the foundation of every blotter from RChems EU:

  1. Active Ingredient Testing (Pre-Blotters):
    • High-Performance Liquid Chromatography (HPLC-DAD): Quantitative analysis at 220 nm and 254 nm. Minimum acceptance criterion: ≥99.0% peak area purity.
    • Liquid Chromatography-Mass Spectrometry (LC-MS): Confirms molecular ion [M+H]⁺ = 343.1 and detects trace-level organic impurities down to 0.05%.
    • Nuclear Magnetic Resonance (NMR): Both proton (¹H) and carbon-13 (¹³C) NMR verify the correct thienodiazepine ring system, 2-chlorophenyl substitution (characteristic aromatic splitting), and ethyl and methyl substituents. Any spectral deviation triggers batch rejection.
    • Residual Solvent Analysis (GC-MS): Ensures compliance with ICH limits for Class 2 and Class 3 solvents.
    • Heavy Metal Testing (ICP-MS): Confirms levels below 20 ppm for lead, arsenic, cadmium, and mercury.
  2. Post-Blotters Quality Control:
    • Homogeneity Testing: Randomly selected blotters are assayed to confirm consistent 1mg ±5% active content.
    • Extraction Efficiency Testing: Confirms complete release of active compound from the blotter matrix in standard laboratory solvents (ethanol, DMSO).

Each batch is assigned a unique lot number, and a Certificate of Analysis (COA) for the active ingredient is available upon request. This rigorous testing ensures that when you buy Etizolam 1mg blotters for research, you receive a consistent, high-precision product.

FAQ Section

1. What are Etizolam 1mg blotters used for in research?

Etizolam 1mg blotters are pre-dosed absorbent paper units containing Etizolam (CAS 40054-69-1), a thienodiazepine derivative. They are used in neuropharmacological research to study GABA-A receptor binding affinity and positive allosteric modulation, the effects of thiophene ring substitution (vs. benzene ring in classical benzodiazepines) on receptor pharmacology, and structure-activity relationships among thienodiazepine derivatives. The blotter format is particularly valuable for studies requiring solid-phase extraction or controlled release from the blotter matrix.

2. How do I prepare the blotters for use in assays?

Blotters can be placed in an appropriate organic solvent (e.g., ethanol, methanol, or DMSO) to extract the active compound. The exact concentration should be verified by UV spectrophotometry or HPLC after extraction. The blotter paper is designed to release the active compound completely into these solvents. For aqueous buffers, first extract the blotter in a small volume of ethanol or DMSO, then dilute with buffer (keeping final organic solvent concentration below 1-2% to avoid interference with biological assays).

3. Are the 1mg blotters homogeneous in content?

Yes. Every blotter in a given batch contains a verified 1 mg (±5%) of Etizolam. RChems EU performs random sampling and content uniformity testing on each production batch to ensure consistent dosage across all blotters. The Certificate of Analysis (COA) includes content uniformity data upon request.

Legality depends on your jurisdiction. Etizolam is not federally scheduled in the US but may be considered a controlled substance analogue under the Federal Analogue Act (21 U.S.C. § 813) if intended for human consumption. Several countries (including Japan, China, Germany, Italy, and the UK) have specific controls on Etizolam. You must check your local regulations before ordering. RChems EU ships on the condition that you assume full legal responsibility.

5. How discreet is the shipping from RChems EU?

The difference is the form factor: blotters are pre-dosed 1 mg units on absorbent paper, while powder requires manual weighing on an analytical balance. Blotters offer convenience, reduced measurement error, and a compact, stable storage format. Powder offers flexibility for custom dosing but requires precise weighing equipment and technique.

9. What is the difference between Etizolam and classical benzodiazepines (e.g., alprazolam)?

The key structural difference is the heterocyclic ring fused to the diazepine core:

  • Classical benzodiazepines (alprazolam, diazepam) have a benzene ring
  • Etizolam has a thiophene ring (sulfur-containing five-membered aromatic ring)

In GABA-A receptor research, the thiophene ring substitution alters electronic properties, receptor binding affinity, metabolic stability, and selectivity for different GABA-A receptor subtypes. Comparing Etizolam with classical benzodiazepines allows researchers to map the impact of heterocyclic ring substitution on thienodiazepine vs. benzodiazepine pharmacology.

10. What is the significance of CAS number 40054-69-1?

CAS number 40054-69-1 is the unique Chemical Abstracts Service identifier for Etizolam. Researchers can use this CAS number for precise chemical identification when ordering reference standards, searching scientific literature, or documenting research materials. It is the standard identifier across analytical chemistry, forensic toxicology, and pharmacological research.
