Chemical Structure
Description
8-Chloroimidazo[1,2-a]pyridine-2-carboxylic Acid (C8H5ClN2O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; 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).
8-Chloroimidazo[1,2-a]pyridine-2-carboxylic Acid (CAS 1020038-45-2), molecular formula C8H5ClN2O2 and molecular weight 196.59 g/mol, is a CATO reference standard with documented purity and traceability.
