Description
CATO supplies Diquafosol Impurity 15 (CAS 10003-94-8), a pharmacopoeial impurity reference standard (molecular formula C9H16N2O18P4, MW 564.12 g/mol) used for the identification and quantification of trace impurities in APIs.
Diquafosol Impurity 15 (C9H16N2O18P4) contains a carbohydrate-derived structure, an amide group, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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), Diquafosol Impurity 15 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.
