Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-Oxobenzo[d][1,3]oxathiol-5-yl 2-bromobenzoate (CAS 337496-15-8), molecular formula C14H7BrO4S and molecular weight 351.17 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-Oxobenzo[d][1,3]oxathiol-5-yl 2-bromobenzoate (C14H7BrO4S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, a polycyclic aromatic 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
CATO manufactures 2-Oxobenzo[d][1,3]oxathiol-5-yl 2-bromobenzoate 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.
