N-[(E)-3-(4-Chlorophenyl)-2-propenoyl]-4-methylbenzenesulfonohydrazide (CAS 478029-76-4) is a high-purity analytical reference standard with the molecular formula C16H15ClN2O3S and a molecular weight of 350.82 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, N-[(E)-3-(4-Chlorophenyl)-2-propenoyl]-4-methylbenzenesulfonohydrazide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 350.82 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
