Chemical Structure

Fluvastatin Impurity 19 CAS CATO-C4X-165119 chemical structure

Description

The occurrence of Fluvastatin Impurity 19 is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Fluvastatin Impurity 19 (CAS CATO-C4X-165119), a pharmacopoeial impurity reference standard (molecular formula C17H16FN, MW 253.31 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Fluvastatin Impurity 19 (C17H16FN) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 253.31 g/mol, it falls into the medium-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), Fluvastatin Impurity 19 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.
