Fosfomycin Trometamol EP Impurity A Disodium Salt CAS CATO-C4X-13166

Description

Compared with other compounds in its class, the molecular weight of 177.05 g/mol gives Fosfomycin Trometamol EP Impurity A Disodium Salt distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

As a process- or degradation-related impurity, Fosfomycin Trometamol EP Impurity A Disodium Salt (CAS CATO-C4X-13166, C3H7O5PNa) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Owing to a phosphate ester group, a carboxylic acid group, an ether linkage, Fosfomycin Trometamol EP Impurity A Disodium Salt is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 177.05 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

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 Trometamol EP Impurity A Disodium Salt 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.
