Tocopherol Impurity 14 CAS CATO-C4X-119514

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Tocopherol Impurity 14.

CATO supplies Tocopherol Impurity 14 (CAS CATO-C4X-119514), a pharmacopoeial impurity reference standard (molecular formula C40H76, MW 557.03 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Tocopherol Impurity 14 (C40H76) contains an organic framework. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 557.03 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), Tocopherol Impurity 14 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.
