Chemical Structure
Description
3-Methanesulfonylimidazo[1,5-a]pyridine-1-carboxylic acid (C9H8N2O4S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
3-Methanesulfonylimidazo[1,5-a]pyridine-1-carboxylic acid (CAS 76259-07-9), molecular formula C9H8N2O4S and molecular weight 240.24 g/mol, is a CATO reference standard with documented purity and traceability.
