Chemical Structure

Fosfomycin Impurity 23 CAS CATO-C4X-131623 chemical structure

Description

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.

As a process- or degradation-related impurity, Fosfomycin Impurity 23 (CAS CATO-C4X-131623, C4H11O5P) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Based on its molecular formula C4H11O5P, Fosfomycin Impurity 23 contains a carbohydrate-derived structure, a phosphate ester group; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 170.10 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.

CATO manufactures Fosfomycin Impurity 23 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.
