Chemical Structure
Description
4-(Methylsulfonyl)-1-naphthaldehyde (C12H10O3S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, 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-(Methylsulfonyl)-1-naphthaldehyde (CAS 282728-19-2), molecular formula C12H10O3S and molecular weight 234.27 g/mol, is a CATO reference standard with documented purity and traceability.
