Chemical Structure
Description
methyl 8-bromo-[1,2,4]triazolo[1,5-a]pyridine-2-carboxylate (CAS 1159811-45-6), molecular formula C8H14BrN3O2 and molecular weight 264.12 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, methyl 8-bromo-[1,2,4]triazolo[1,5-a]pyridine-2-carboxylate is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 264.12 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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 methyl 8-bromo-[1,2,4]triazolo[1,5-a]pyridine-2-carboxylate 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.
