Chemical Structure

Benzyl (S)-4-(trifluoromethyl)-1,2,3-oxathiazolidine-3-carboxylate 2,2-dioxide CAS 2920746-96-7 chemical structure

Description

The occurrence of Benzyl (S)-4-(trifluoromethyl)-1,2,3-oxathiazolidine-3-carboxylate 2,2-dioxide is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Benzyl (S)-4-(trifluoromethyl)-1,2,3-oxathiazolidine-3-carboxylate 2,2-dioxide (CAS 2920746-96-7), molecular formula C11H10F3NO5S and molecular weight 325.26 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Benzyl (S)-4-(trifluoromethyl)-1,2,3-oxathiazolidine-3-carboxylate 2,2-dioxide (C11H10F3NO5S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), Benzyl (S)-4-(trifluoromethyl)-1,2,3-oxathiazolidine-3-carboxylate 2,2-dioxide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
