Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 7-Bromo-2-(3-methoxyphenyl)-[1,2,4]triazolo[1,5-a]pyridine (CAS 1380331-74-7), a certified reference material (molecular formula C13H10BrN3O, MW 304.14 g/mol) for analytical method development and quality control.
The molecular framework of 7-Bromo-2-(3-methoxyphenyl)-[1,2,4]triazolo[1,5-a]pyridine (C13H10BrN3O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
