N-(1,1,2,2-Tetrafluoroethyl-N-methyl)benzene-sulfonamide CAS 31375-11-8

Description

The molecular framework of N-(1,1,2,2-Tetrafluoroethyl-N-methyl)benzene-sulfonamide (C9H9F4NO2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

CATO supplies N-(1,1,2,2-Tetrafluoroethyl-N-methyl)benzene-sulfonamide (CAS 31375-11-8), a certified reference material (molecular formula C9H9F4NO2S, MW 271.23 g/mol) for analytical method development and quality control.

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.
