Description
Ceftizoxime Open-ring Ethyl Ester (CAS CATO-C4X-179332), molecular formula C15H19N5O6S2 and molecular weight 429.47 g/mol, is a CATO reference standard with documented purity and traceability.
Ceftizoxime Open-ring Ethyl Ester (C15H19N5O6S2) 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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), Ceftizoxime Open-ring Ethyl Ester 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.
