Chemical Structure
Description
The occurrence of Cefmetazole Impurity 58 is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Cefmetazole Impurity 58 (CAS CATO-C4X-150758), a pharmacopoeial impurity reference standard (molecular formula C4H6O3S2, MW 166.22 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C4H6O3S2, Cefmetazole Impurity 58 contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 166.22 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.
Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
CATO manufactures Cefmetazole Impurity 58 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.
