Cefoxitin EP Impurity A Potassium Salt CAS 37051-16-4

Description

The occurrence of Cefoxitin EP Impurity A Potassium Salt is closely related to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Cefoxitin EP Impurity A Potassium Salt (CAS 37051-16-4), molecular formula C15H15N2O6S2K and molecular weight 422.51 g/mol, is a CATO reference standard with documented purity and traceability.

Cefoxitin EP Impurity A Potassium Salt (C15H15N2O6S2K) 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.

CATO manufactures Cefoxitin EP Impurity A Potassium Salt 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.
