Chemical Structure
Description
n-(2-Chloropyridin-4-yl)methanesulfonamide (C6H7ClN2O2S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
n-(2-Chloropyridin-4-yl)methanesulfonamide (CAS 1247737-27-4), molecular formula C6H7ClN2O2S and molecular weight 206.65 g/mol, is a CATO reference standard with documented purity and traceability.
