Chemical Structure
Description
The occurrence of 4-Nitro-N-[4-(trifluoromethyl)phenyl]benzenesulfonamide is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 4-Nitro-N-[4-(trifluoromethyl)phenyl]benzenesulfonamide (CAS 312-51-6), a certified reference material (molecular formula C13H9F3N2O4S, MW 346.28 g/mol) for analytical method development and quality control.
Structurally, 4-Nitro-N-[4-(trifluoromethyl)phenyl]benzenesulfonamide (C13H9F3N2O4S) 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 346.28 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).
