Chemical Structure

Pitavastatin Impurity 111 CAS CATO-C4X-1037111 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 Pitavastatin Impurity 111.

CATO supplies Pitavastatin Impurity 111 (CAS CATO-C4X-1037111), a pharmacopoeial impurity reference standard (molecular formula C25H20FNO4, MW 417.43 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Pitavastatin Impurity 111 (C25H20FNO4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 16.0, corresponding to approximately 16 ring(s) or double-bond equivalent(s). With a molecular weight of 417.43 g/mol, it falls into the moderately-high-molecular-weight range. 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), Pitavastatin Impurity 111 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.
