Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Tert-butyl (S)-4-(3-bromophenyl)-1,2,3-oxathiazolidine-3-carboxylate 2,2-dioxide (CAS 1379546-88-9) is a high-purity analytical reference standard with the molecular formula C13H16BrNO5S and a molecular weight of 378.24 g/mol.
Based on its molecular formula C13H16BrNO5S, Tert-butyl (S)-4-(3-bromophenyl)-1,2,3-oxathiazolidine-3-carboxylate 2,2-dioxide contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 378.24 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
