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 2,2-Difluoro-2-(Methylsulfanyl)-1-Phenylethanone (CAS 192862-16-1), a certified reference material (molecular formula C9H8F2OS, MW 202.22 g/mol) for analytical method development and quality control.
Owing to sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system, 2,2-Difluoro-2-(Methylsulfanyl)-1-Phenylethanone is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 202.22 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
