Chemical Structure

3-Bromo-2-chloro-5-nitrobenzene-1-sulfonyl chloride CAS 1249673-60-6 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-Bromo-2-chloro-5-nitrobenzene-1-sulfonyl chloride.

CATO supplies 3-Bromo-2-chloro-5-nitrobenzene-1-sulfonyl chloride (CAS 1249673-60-6), a certified reference material (molecular formula C6H2BrCl2NO4S, MW 334.96 g/mol) for analytical method development and quality control.

The molecular framework of 3-Bromo-2-chloro-5-nitrobenzene-1-sulfonyl chloride (C6H2BrCl2NO4S) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/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.

As a certified reference material (CRM), 3-Bromo-2-chloro-5-nitrobenzene-1-sulfonyl chloride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
