Ethyl 5-chloro-3H-imidazo[4,5-b]pyridine-2-carboxylate CAS 1044772-75-9

Description

The occurrence of Ethyl 5-chloro-3H-imidazo[4,5-b]pyridine-2-carboxylate is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Ethyl 5-chloro-3H-imidazo[4,5-b]pyridine-2-carboxylate (CAS 1044772-75-9), a certified reference material (molecular formula C9H8ClN3O2, MW 225.63 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, Ethyl 5-chloro-3H-imidazo[4,5-b]pyridine-2-carboxylate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 225.63 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
