Chemical Structure

Foscarnet Sodium EP Impurity A CAS 72305-00-1 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 Foscarnet Sodium EP Impurity A.

As a process- or degradation-related impurity, Foscarnet Sodium EP Impurity A (CAS 72305-00-1, C3H5O5PNa) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Foscarnet Sodium EP Impurity A (C3H5O5PNa) contains a phosphate ester group, a carboxylic acid 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.

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), Foscarnet Sodium EP Impurity A 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.
