Chemical Structure
Description
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, N-(2-Chlorobenzylidene)-4-methylbenzenesulfonamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 293.77 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
N-(2-Chlorobenzylidene)-4-methylbenzenesulfonamide (CAS 150552-84-4), molecular formula C14H12ClNO2S and molecular weight 293.77 g/mol, is a CATO reference standard with documented purity and traceability.
