Chemical Structure
Description
4-Chloro-2-(methylsulfonyl)pyrimidine (C5H5ClN2O2S) contains an amide group, a sulfone group, a carboxylic acid 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 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).
4-Chloro-2-(methylsulfonyl)pyrimidine (CAS 97229-11-3), molecular formula C5H5ClN2O2S and molecular weight 192.62 g/mol, is a CATO reference standard with documented purity and traceability.
