N-(5-Bromo-2-chloro-3-pyridyl)benzenesulfonamide, 97% CAS 1083326-17-3

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N-(5-Bromo-2-chloro-3-pyridyl)benzenesulfonamide, 97%.

N-(5-Bromo-2-chloro-3-pyridyl)benzenesulfonamide, 97% (CAS 1083326-17-3), molecular formula C11H8BrClN2O2S and molecular weight 347.62 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine/bromine substitution, N-(5-Bromo-2-chloro-3-pyridyl)benzenesulfonamide, 97% is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 347.62 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

CATO manufactures N-(5-Bromo-2-chloro-3-pyridyl)benzenesulfonamide, 97% under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
