Description
As a certified reference material (CRM), Cefotaxime Sodium Salt 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.
Cefotaxime Sodium Salt (CAS 64485-93-4), molecular formula C16H16N5O7S2Na and molecular weight 477.44 g/mol, is a CATO reference standard with documented purity and traceability.
Cefotaxime Sodium Salt (C16H16N5O7S2Na) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
