Chemical Structure
Description
1-(2-Chloro-4-(methylsulfonyl)phenyl)piperidine-4-carboxylic acid (C13H16ClNO4S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
1-(2-Chloro-4-(methylsulfonyl)phenyl)piperidine-4-carboxylic acid (CAS 942474-34-2), molecular formula C13H16ClNO4S and molecular weight 317.79 g/mol, is a CATO reference standard with documented purity and traceability.
