Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 2-Bromo-1-(3-fluoro-5-(trifluoromethyl)phenyl)ethanone (CAS 202664-38-8), a certified reference material (molecular formula C9H5BrF4O, MW 285.03 g/mol) for analytical method development and quality control.
2-Bromo-1-(3-fluoro-5-(trifluoromethyl)phenyl)ethanone (C9H5BrF4O) contains a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
