Chemical Structure

Fosfomycin Impurity 79 CAS CATO-C4X-131679 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 276.12 g/mol gives Fosfomycin Impurity 79 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Fosfomycin Impurity 79 (CAS CATO-C4X-131679), a pharmacopoeial impurity reference standard (molecular formula C6H14O8P2, MW 276.12 g/mol) used for the identification and quantification of trace impurities in APIs.

Fosfomycin Impurity 79 (C6H14O8P2) contains a carbohydrate-derived structure, a phosphate ester group. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions.

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 certified reference material (CRM), Fosfomycin Impurity 79 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
