5-bromo-[1,2,4]triazolo[4,3-a]pyridine-3-carboxylic acid CAS 1782429-11-1

Description

The occurrence of 5-bromo-[1,2,4]triazolo[4,3-a]pyridine-3-carboxylic acid is closely related to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 5-bromo-[1,2,4]triazolo[4,3-a]pyridine-3-carboxylic acid (CAS 1782429-11-1), a certified reference material (molecular formula C7H12BrN3O2, MW 250.09 g/mol) for analytical method development and quality control.

Based on its molecular formula C7H12BrN3O2, 5-bromo-[1,2,4]triazolo[4,3-a]pyridine-3-carboxylic acid contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 250.09 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.

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.
