Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 176.01 g/mol gives 3-bromo-4,5-dimethyl-4H-1,2,4-triazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 3-bromo-4,5-dimethyl-4H-1,2,4-triazole (CAS 56616-84-3), a certified reference material (molecular formula C4H6BrN3, MW 176.01 g/mol) for analytical method development and quality control.
The molecular framework of 3-bromo-4,5-dimethyl-4H-1,2,4-triazole (C4H6BrN3) 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 3-bromo-4,5-dimethyl-4H-1,2,4-triazole 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.
