Chemical Structure

7-Bromobenzo[c][1,2,5]thiadiazole-4-sulfonyl chloride CAS 41512-06-5 chemical structure

Description

7-Bromobenzo[c][1,2,5]thiadiazole-4-sulfonyl chloride (CAS 41512-06-5) is a high-purity analytical reference standard with the molecular formula C6H2BrClN2O2S2 and a molecular weight of 313.58 g/mol.

The molecular framework of 7-Bromobenzo[c][1,2,5]thiadiazole-4-sulfonyl chloride (C6H2BrClN2O2S2) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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 7-Bromobenzo[c][1,2,5]thiadiazole-4-sulfonyl chloride 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.
