4-(4-Fluoro-3-methylbenzenesulfonamido)benzoic acid (CAS 327091-30-5), molecular formula C14H12FNO4S and molecular weight 309.31 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 4-(4-Fluoro-3-methylbenzenesulfonamido)benzoic acid (C14H12FNO4S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 309.31 g/mol, it falls into the moderately-high-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.
