Description
CATO manufactures 1-Bromo-4-(ethylsulfonyl)benzene 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.
1-Bromo-4-(ethylsulfonyl)benzene (CAS 26732-20-7) is a high-purity analytical reference standard with the molecular formula C8H9BrO2S and a molecular weight of 249.12 g/mol.
The molecular framework of 1-Bromo-4-(ethylsulfonyl)benzene (C8H9BrO2S) 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 the polarity and ionization state of its functional groups, 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).
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.
