Chemical Structure
Description
The occurrence of Diquafosol Impurity 2 is closely related to a carbohydrate-derived structure, an amide group, a phosphate ester group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Diquafosol Impurity 2 (CAS 1402828-42-5) is a certified pharmaceutical impurity reference standard with the molecular formula C9H11N2O18P4Na and a molecular weight of 582.07 g/mol.
Owing to a carbohydrate-derived structure, an amide group, a phosphate ester group, Diquafosol Impurity 2 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 582.07 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 2 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.
