Chemical Structure
Description
The molecular framework of 5’-Bromo-2’-hydroxy-2-phenylacetophenone (C14H11BrO2) is characterized by 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
5’-Bromo-2’-hydroxy-2-phenylacetophenone (CAS 54981-34-9) is a high-purity analytical reference standard with the molecular formula C14H11BrO2 and a molecular weight of 291.14 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
