Description
CATO manufactures 2-(4-Bromophenyl)-1,3,2-dioxaborinane 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.
2-(4-Bromophenyl)-1,3,2-dioxaborinane (CAS 54947-91-0) is a high-purity analytical reference standard with the molecular formula C9H10BBrO2 and a molecular weight of 240.89 g/mol.
The molecular framework of 2-(4-Bromophenyl)-1,3,2-dioxaborinane (C9H10BBrO2) is characterized by 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 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).
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.
