Deschloroetizolam

Deschloroetizolam

Professional Thienotriazolodiazepine Reference Standards for Global Research & Analytical Applications

Deschloroetizolam (2-ethyl-9-methyl-6,8,9,10-tetrahydro-4H-thieno[3,2-f][1,2,4]triazolo[4,3-a][1,4]diazepine, also known as etizolam-deschloro, CAS 40054-69-1) is a synthetic thienotriazolodiazepine compound utilised as an analytical reference standard in forensic toxicology, NPS monitoring programmes, and GABA receptor pharmacology research. As the deschloro analogue of etizolam, featuring a thiophene ring in place of the chlorophenyl moiety, this compound serves critical functions in laboratories investigating bioisosteric replacements, structure-activity relationships, and emerging thienodiazepine identification across Europe, North America, Asia-Pacific, and international professional markets.

At realchemsupply.com, we supply high-purity Deschloroetizolam analytical standards manufactured to stringent industrial specifications for qualified organisations worldwide. Our international B2B chemical supply infrastructure supports forensic laboratories, universities, research institutions, analytical facilities, and industrial manufacturers requiring consistent, documented reference materials for thienodiazepine differentiation and bioisostere research applications.

What Are Deschloroetizolam Products?

Chemical Classification and Overview

Deschloroetizolam belongs to the thienotriazolodiazepine chemical class, characterised by a fused thiophene ring replacing the phenyl group found in classical benzodiazepines, combined with a triazole ring fusion. This bioisosteric replacement creates distinct physicochemical and pharmacological properties compared to phenyl-based analogues. The systematic IUPAC designation reflects this thiophene-containing polycyclic structure.

Molecular Formula: C₁₃H₁₅N₅S
Molecular Weight: 273.36 g/mol
CAS Registry Number: 40054-69-1
Chemical Class: Thienotriazolodiazepine; Thienodiazepine derivative; Bioisosteric benzodiazepine analogue

The absence of the chlorine substituent and the presence of the thiophene ring distinguish Deschloroetizolam from etizolam, creating differences in lipophilicity, metabolic stability, and receptor binding characteristics. As a bioisosteric analogue, this compound provides valuable comparative data for structure-activity relationship studies investigating heterocyclic ring substitutions in GABA modulators.

General Characteristics and Industrial Relevance

Thienodiazepine reference standards like Deschloroetizolam serve essential functions within professional chemical analysis and research workflows:

  • Forensic Toxicology: Identification and quantification in biological matrices for post-mortem investigations, clinical toxicology, and impaired driving assessments involving novel thienodiazepine analogues
  • NPS Surveillance: Early warning system participation and seized material characterisation for border control monitoring thienodiazepine emergence as benzodiazepine alternatives
  • Bioisostere Research: Structure-activity relationship studies comparing thiophene versus phenyl ring substitutions in GABA-A receptor modulation
  • Metabolism Studies: Investigation of metabolic pathways distinct from chlorinated phenyl analogues, including thiophene oxidation and ring cleavage
  • Analytical Method Development: Validation of chromatographic techniques for thienodiazepine differentiation from classical benzodiazepines

Professional organisations source these materials through qualified B2B chemical suppliers to ensure batch consistency, documented purity, and regulatory compliance for forensic defensibility and research reproducibility.

Procurement Considerations

When sourcing Deschloroetizolam reference standards, professional buyers evaluate:

  • Specification Documentation: Comprehensive analytical data including HPLC purity, NMR confirmation with thiophene characteristic signals, and high-resolution mass spectrometry
