Tadalafil EP Impurity G CAS 2520114-46-7

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Tadalafil EP Impurity G.

CATO supplies Tadalafil EP Impurity G (CAS 2520114-46-7), a pharmacopoeial impurity reference standard (molecular formula C22H17N3O5, MW 403.39 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C22H17N3O5, Tadalafil EP Impurity G contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 403.39 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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), Tadalafil EP Impurity G 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.
