2-Chloro-[1,2,4]triazolo[1,5-a]pyridine-6-carboxylic acid CAS 1546151-96-5

Description

The occurrence of 2-Chloro-[1,2,4]triazolo[1,5-a]pyridine-6-carboxylic acid is closely related to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-Chloro-[1,2,4]triazolo[1,5-a]pyridine-6-carboxylic acid (CAS 1546151-96-5) is a high-purity analytical reference standard with the molecular formula C7H4ClN3O2 and a molecular weight of 197.58 g/mol.

Based on its molecular formula C7H4ClN3O2, 2-Chloro-[1,2,4]triazolo[1,5-a]pyridine-6-carboxylic acid contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 197.58 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
