Chemical Structure

N-(3-Fluoro-4-methylphenyl)-4-methylbenzenesulfonamide CAS 876556-75-1 chemical structure

Description

The occurrence of N-(3-Fluoro-4-methylphenyl)-4-methylbenzenesulfonamide 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 N-(3-Fluoro-4-methylphenyl)-4-methylbenzenesulfonamide (CAS 876556-75-1), a certified reference material (molecular formula C14H14FNO2S, MW 279.33 g/mol) for analytical method development and quality control.

Based on its molecular formula C14H14FNO2S, N-(3-Fluoro-4-methylphenyl)-4-methylbenzenesulfonamide contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 279.33 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
