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.
1-(5-(1,3-Dioxolan-2-yl)thiophen-2-yl)-2,2,2-trifluoroethan-1-one (CAS 898772-29-7), molecular formula C9H7F3O3S and molecular weight 252.21 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system, 1-(5-(1,3-Dioxolan-2-yl)thiophen-2-yl)-2,2,2-trifluoroethan-1-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 252.21 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
