Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Bromo-6,7,8,9-tetrahydro-5H-[1,2,4]triazolo[1,5-a][1,4]diazepine.
2-Bromo-6,7,8,9-tetrahydro-5H-[1,2,4]triazolo[1,5-a][1,4]diazepine (CAS 1260663-43-1), molecular formula C6H9BrN4 and molecular weight 217.07 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-Bromo-6,7,8,9-tetrahydro-5H-[1,2,4]triazolo[1,5-a][1,4]diazepine (C6H9BrN4) is characterized by a nitrile group, bromine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 2-Bromo-6,7,8,9-tetrahydro-5H-[1,2,4]triazolo[1,5-a][1,4]diazepine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
