Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 446.37 g/mol gives Cefuroxime sodium distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Cefuroxime sodium (CAS 56238-63-2) is a high-purity analytical reference standard with the molecular formula C16H15N4O8SNa and a molecular weight of 446.37 g/mol.
The molecular framework of Cefuroxime sodium (C16H15N4O8SNa) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures Cefuroxime sodium under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
