Description
CATO manufactures 2-bromo-1-(4-hydroxyphenyl)propan-1-one 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-bromo-1-(4-hydroxyphenyl)propan-1-one (CAS 53946-87-5), molecular formula C9H9BrO2 and molecular weight 229.07 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-bromo-1-(4-hydroxyphenyl)propan-1-one (C9H9BrO2) 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 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.
