Chemical Structure
Description
(S)-N-(4-chlorobenzylidene)-2-methylpropane-2-sulfinamide (C11H14ClNOS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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).
(S)-N-(4-chlorobenzylidene)-2-methylpropane-2-sulfinamide (CAS 851513-47-8), molecular formula C11H14ClNOS and molecular weight 243.75 g/mol, is a CATO reference standard with documented purity and traceability.
