Purity & Testing

Reproducibility in GABA-A receptor and neuropharmacology research depends critically on compound purity. 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 from RChems EU is subjected to a multi-laboratory quality control workflow:

  1. High-Performance Liquid Chromatography (HPLC-DAD): Quantitative analysis at 220 nm and 254 nm. Minimum acceptance criterion: ≥99.0% peak area purity.
  2. Liquid Chromatography-Mass Spectrometry (LC-MS): Confirms molecular ion [M+H]⁺ = 343.1 and detects trace-level organic impurities down to 0.05%.
  3. 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—particularly signals indicative of incorrect substitution—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 Etizolam Pure for research, you receive a compound that performs consistently from order to order.

8. 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 and receptor binding affinity
  • Metabolic stability and elimination pathways
  • Selectivity for different GABA-A receptor subtypes
  • Overall pharmacokinetic profile in research models

Comparing Etizolam with classical benzodiazepines allows researchers to map the impact of heterocyclic ring substitution on thienodiazepine vs. benzodiazepine pharmacology.

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

CAS number 40054-69-1 is the unique Chemical Abstracts Service identifier for Etizolam.
