Chemical Structure
Description
The occurrence of 6,7,8,9-Tetrahydro-5H-[1,2,4]triazolo[4,3-d][1,4]diazepine hydrochloride is closely related to a nitrile group, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
6,7,8,9-Tetrahydro-5H-[1,2,4]triazolo[4,3-d][1,4]diazepine hydrochloride (CAS 1956322-33-0), molecular formula C6H10N4HCl and molecular weight 174.63 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrile group, chlorine substitution, 6,7,8,9-Tetrahydro-5H-[1,2,4]triazolo[4,3-d][1,4]diazepine hydrochloride is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 174.63 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures 6,7,8,9-Tetrahydro-5H-[1,2,4]triazolo[4,3-d][1,4]diazepine hydrochloride under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
