Benzyl 4-(2,2,2-trifluoroethyl)-1,2,3-oxathiazolidine-3-carboxylate 2,2-dioxide CAS 2920749-33-1

Description

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

Benzyl 4-(2,2,2-trifluoroethyl)-1,2,3-oxathiazolidine-3-carboxylate 2,2-dioxide (CAS 2920749-33-1), molecular formula C12H12F3NO5S and molecular weight 339.29 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C12H12F3NO5S, Benzyl 4-(2,2,2-trifluoroethyl)-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, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 339.29 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
