49701-24-8 4-Amino-2,5-dimethoxy-N-methylbenzenesulphonamide Benzenesulfonamide, 4-amino-2,5-dimethoxy-N-methyl- EINECS 256-435-3 N-Methyl-4-amino-2,5-dimethoxybenzenesulfonamide EC 256-435-3 (CAS 49701-24-8), molecular formula C9H14N2O4S and molecular weight 246.28 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 49701-24-8 4-Amino-2,5-dimethoxy-N-methylbenzenesulphonamide Benzenesulfonamide, 4-amino-2,5-dimethoxy-N-methyl- EINECS 256-435-3 N-Methyl-4-amino-2,5-dimethoxybenzenesulfonamide EC 256-435-3 (C9H14N2O4S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 246.28 g/mol, it falls into the medium-molecular-weight range. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
