Chemical Structure
Description
The molecular framework of 4-[(4-bromobenzene)sulfonyl]butanoic acid (C10H11BrO4S) is characterized by 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 its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
4-[(4-bromobenzene)sulfonyl]butanoic acid (CAS 1018522-96-7) is a high-purity analytical reference standard with the molecular formula C10H11BrO4S and a molecular weight of 307.16 g/mol.
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 4-[(4-bromobenzene)sulfonyl]butanoic acid 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.
