Chemical Structure

Sildenafil Impurity 70 CAS 90324-69-9 chemical structure

Description

Sildenafil Impurity 70 (C5H12N2O) contains an amide group, a hydroxyl group, an ether linkage. Its physicochemical properties are representative of its class; 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.

Sildenafil Impurity 70 (CAS 90324-69-9) is a certified pharmaceutical impurity reference standard with the molecular formula C5H12N2O and a molecular weight of 116.16 g/mol.

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), Sildenafil Impurity 70 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.
