Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Tert-butyl (S)-4-(4-chlorophenyl)-1,2,3-oxathiazolidine-3-carboxylate 2,2-dioxide.
Tert-butyl (S)-4-(4-chlorophenyl)-1,2,3-oxathiazolidine-3-carboxylate 2,2-dioxide (CAS 1379546-77-6) is a high-purity analytical reference standard with the molecular formula C13H16ClNO5S and a molecular weight of 333.79 g/mol.
Tert-butyl (S)-4-(4-chlorophenyl)-1,2,3-oxathiazolidine-3-carboxylate 2,2-dioxide (C13H16ClNO5S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine 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. 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.
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.
