Chemical Structure

2,6-Dibromo-4-(methylsulfonyl)aniline CAS 26595-53-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 329.01 g/mol gives 2,6-Dibromo-4-(methylsulfonyl)aniline distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 2,6-Dibromo-4-(methylsulfonyl)aniline (CAS 26595-53-9), a certified reference material (molecular formula C7H7Br2NO2S, MW 329.01 g/mol) for analytical method development and quality control.

The molecular framework of 2,6-Dibromo-4-(methylsulfonyl)aniline (C7H7Br2NO2S) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. 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. 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.
