Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
5,5-Diethyl-1,3,2-dioxathiane 2,2-dioxide (CAS 120188-69-4), molecular formula C7H14O4S and molecular weight 194.25 g/mol, is a CATO reference standard with documented purity and traceability.
5,5-Diethyl-1,3,2-dioxathiane 2,2-dioxide (C7H14O4S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions.
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.
