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 3,3'-Difluorobenzophenone 345-70-0 AS05226 ATTERCOP-CHM AT133845 BIS(3-FLUOROPHENYL)METHANONE EMOLECULES 497832 (CAS 345-70-0), a certified reference material (molecular formula C13H20F2O, MW 230.29 g/mol) for analytical method development and quality control.
Owing to a hydroxyl group, an ether linkage, fluorine substitution, 3,3'-Difluorobenzophenone 345-70-0 AS05226 ATTERCOP-CHM AT133845 BIS(3-FLUOROPHENYL)METHANONE EMOLECULES 497832 is typically white to off-white low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 230.29 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
