N-(3,5-Dimethylphenyl)-4-fluorobenzenesulfonamide CAS 329941-60-8

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N-(3,5-Dimethylphenyl)-4-fluorobenzenesulfonamide.

N-(3,5-Dimethylphenyl)-4-fluorobenzenesulfonamide (CAS 329941-60-8), molecular formula C14H14FNO2S and molecular weight 279.33 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, N-(3,5-Dimethylphenyl)-4-fluorobenzenesulfonamide (C14H14FNO2S) 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 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 279.33 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
