Chemical Structure

4-(N-(3-(trifluoromethyl)phenyl)sulfamoyl)benzoic acid CAS 321979-21-9 chemical structure

Description

Structurally, 4-(N-(3-(trifluoromethyl)phenyl)sulfamoyl)benzoic acid (C14H10F3NO4S) 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 345.29 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).

4-(N-(3-(trifluoromethyl)phenyl)sulfamoyl)benzoic acid (CAS 321979-21-9), molecular formula C14H10F3NO4S and molecular weight 345.29 g/mol, is a CATO reference standard with documented purity and traceability.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
