5,6-Dibromo-7-methyl-1H,2H,3H-imidazo[4,5-b]pyridin-2-one CAS 2169997-51-5

Description

The occurrence of 5,6-Dibromo-7-methyl-1H,2H,3H-imidazo[4,5-b]pyridin-2-one is closely related to an amide group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 5,6-Dibromo-7-methyl-1H,2H,3H-imidazo[4,5-b]pyridin-2-one (CAS 2169997-51-5), a certified reference material (molecular formula C7H5Br2N3O, MW 306.94 g/mol) for analytical method development and quality control.

5,6-Dibromo-7-methyl-1H,2H,3H-imidazo[4,5-b]pyridin-2-one (C7H5Br2N3O) contains an amide group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
