The occurrence of (5-Bromo-3-methylbenzofuran-2-yl)(phenyl)methanone is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(5-Bromo-3-methylbenzofuran-2-yl)(phenyl)methanone (CAS 303145-25-7), molecular formula C16H11BrO2 and molecular weight 315.16 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C16H11BrO2, (5-Bromo-3-methylbenzofuran-2-yl)(phenyl)methanone contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 315.16 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
