Description
Compared with other compounds in its class, the molecular weight of 554.58 g/mol gives Ceftriaxone distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Ceftriaxone (CAS 73384-59-5), molecular formula C18H18N8O7S3 and molecular weight 554.58 g/mol, is a CATO reference standard with documented purity and traceability.
Ceftriaxone (C18H18N8O7S3) 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).
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 Ceftriaxone 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.
