Chemical Structure

(E)-Cefotaxime S-Oxide CAS CATO-C4X-120131 chemical structure

Description

(E)-Cefotaxime S-Oxide (C16H17N5O8S2) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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).

(E)-Cefotaxime S-Oxide (CAS CATO-C4X-120131) is a high-purity analytical reference standard with the molecular formula C16H17N5O8S2 and a molecular weight of 471.46 g/mol.

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), (E)-Cefotaxime S-Oxide 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.
