Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 174.12 g/mol gives 2,2-Difluoro-1-(3-fluorophenyl)ethan-1-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 2,2-Difluoro-1-(3-fluorophenyl)ethan-1-one (CAS 1271475-01-4), a certified reference material (molecular formula C8H5F3O, MW 174.12 g/mol) for analytical method development and quality control.
2,2-Difluoro-1-(3-fluorophenyl)ethan-1-one (C8H5F3O) contains a hydroxyl group, an ether linkage, fluorine 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).
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.
