Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 319.15 g/mol gives 3-(4-Bromobenzoyl)phenyl acetate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-(4-Bromobenzoyl)phenyl acetate (CAS 890099-61-3), molecular formula C15H11BrO3 and molecular weight 319.15 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, a polycyclic aromatic system, 3-(4-Bromobenzoyl)phenyl acetate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 319.15 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
