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 5-Bromo-1H-1,2,3-triazol-4-amine.
5-Bromo-1H-1,2,3-triazol-4-amine (CAS 1779939-45-5), molecular formula C2H3BrN4 and molecular weight 162.98 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5-Bromo-1H-1,2,3-triazol-4-amine (C2H3BrN4) is characterized by a nitrile group, bromine substitution. 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.
CATO manufactures 5-Bromo-1H-1,2,3-triazol-4-amine 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.
