3H-imidazo[4,5-b]pyridine-7-carboxylic acid CAS 78316-08-2

Description

The occurrence of 3H-imidazo[4,5-b]pyridine-7-carboxylic acid is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 3H-imidazo[4,5-b]pyridine-7-carboxylic acid (CAS 78316-08-2), a certified reference material (molecular formula C7H13N3O2, MW 171.20 g/mol) for analytical method development and quality control.

Based on its molecular formula C7H13N3O2, 3H-imidazo[4,5-b]pyridine-7-carboxylic acid contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 171.20 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
