6-Bromo-2-chloropyridine-3-sulfonamide CAS 1707371-82-1

Description

The occurrence of 6-Bromo-2-chloropyridine-3-sulfonamide is closely related to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

6-Bromo-2-chloropyridine-3-sulfonamide (CAS 1707371-82-1) is a high-purity analytical reference standard with the molecular formula C5H4BrClN2O2S and a molecular weight of 271.52 g/mol.

The molecular framework of 6-Bromo-2-chloropyridine-3-sulfonamide (C5H4BrClN2O2S) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/bromine 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. 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), 6-Bromo-2-chloropyridine-3-sulfonamide 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.
