Chemical Structure

Cefazolin Impurity 58 CAS 1012-29-9 chemical structure

Description

The occurrence of Cefazolin Impurity 58 is closely related to a nitrile group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Cefazolin Impurity 58 (CAS 1012-29-9), a pharmacopoeial impurity reference standard (molecular formula C11H22N2, MW 182.31 g/mol) used for the identification and quantification of trace impurities in APIs.

Cefazolin Impurity 58 (C11H22N2) contains a nitrile group. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.

CATO manufactures Cefazolin 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.
