CATO manufactures Fosfomycin Impurity 36 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.
CATO supplies Fosfomycin Impurity 36 (CAS CATO-C4X-131636), a pharmacopoeial impurity reference standard (molecular formula C5H13O5P, MW 184.13 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C5H13O5P, Fosfomycin Impurity 36 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 184.13 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.
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.
