Chemical Structure

Cefradine Impurity 18 CAS CATO-C4X-121518 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Cefradine Impurity 18.

As a process- or degradation-related impurity, Cefradine Impurity 18 (CAS CATO-C4X-121518, C9H13NO2C2H4O2) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Cefradine Impurity 18 (C9H13NO2C2H4O2) contains an amino-acid-derived structure, an amide 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.

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 Cefradine Impurity 18 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.
