Chemical Structure

4-Methoxy-N-(m-tolyl)benzenesulfonamide CAS 7230-53-7 chemical structure

Description

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.

4-Methoxy-N-(m-tolyl)benzenesulfonamide (CAS 7230-53-7), molecular formula C14H15NO3S and molecular weight 277.34 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 4-Methoxy-N-(m-tolyl)benzenesulfonamide (C14H15NO3S) 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 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 277.34 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).

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.
