Chemical Structure
Description
8-bromo-2-ethylsulfanyl-6-(trifluoromethyl)chromen-4-one (CAS 2715285-50-8), molecular formula C12H16BrF3O2S and molecular weight 361.22 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C12H16BrF3O2S, 8-bromo-2-ethylsulfanyl-6-(trifluoromethyl)chromen-4-one contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 361.22 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.
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.
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.
