Chemical Structure
Description
6-Methoxyimidazo[1,2-a]pyridine-3-carboxylic acid (C9H8N2O3) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
CATO supplies 6-Methoxyimidazo[1,2-a]pyridine-3-carboxylic acid (CAS 944896-44-0), a certified reference material (molecular formula C9H8N2O3, MW 192.17 g/mol) for analytical method development and quality control.
