4-Bromo-N-butyl-3-(trifluoromethyl)benzenesulfonamide CAS 1020253-05-7

Description

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

4-Bromo-N-butyl-3-(trifluoromethyl)benzenesulfonamide (CAS 1020253-05-7) is a high-purity analytical reference standard with the molecular formula C11H13BrF3NO2S and a molecular weight of 360.19 g/mol.

The molecular framework of 4-Bromo-N-butyl-3-(trifluoromethyl)benzenesulfonamide (C11H13BrF3NO2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/bromine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).

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.
