Chemical Structure
Description
Tert-butyl (S)-4-(4-fluorophenyl)-1,2,3-oxathiazolidine-3-carboxylate 2,2-dioxide (CAS 1379546-50-5) is a high-purity analytical reference standard with the molecular formula C13H16FNO5S and a molecular weight of 317.33 g/mol.
Tert-butyl (S)-4-(4-fluorophenyl)-1,2,3-oxathiazolidine-3-carboxylate 2,2-dioxide (C13H16FNO5S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
