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 3-(2-Bromo-3-methylphenyl)-[1,2,4]triazolo[4,3-a]pyridine.
CATO supplies 3-(2-Bromo-3-methylphenyl)-[1,2,4]triazolo[4,3-a]pyridine (CAS 1319196-83-2), a certified reference material (molecular formula C13H10BrN3, MW 288.14 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution, 3-(2-Bromo-3-methylphenyl)-[1,2,4]triazolo[4,3-a]pyridine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 288.14 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).
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 3-(2-Bromo-3-methylphenyl)-[1,2,4]triazolo[4,3-a]pyridine 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.
