Chemical Structure
Description
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.
(2,4-difluorophenyl)[3-(methylsulfanyl)phenyl]methanone (CAS 1332345-21-7), molecular formula C14H10F2OS and molecular weight 264.29 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system, (2,4-difluorophenyl)[3-(methylsulfanyl)phenyl]methanone is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 264.29 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
