Chemical Structure
Description
1-[(4R)-2,2-Dimethyl-1,3-Dioxolan-4-Yl]-2,2,2-Trifluoroethanone (CAS 162932-23-2), molecular formula C7H9F3O3 and molecular weight 198.14 g/mol, is a CATO reference standard with documented purity and traceability.
1-[(4R)-2,2-Dimethyl-1,3-Dioxolan-4-Yl]-2,2,2-Trifluoroethanone (C7H9F3O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
