Chemical Structure
Description
As a certified reference material (CRM), Tocopherol Impurity 30 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.
CATO supplies Tocopherol Impurity 30 (CAS CATO-C4X-119530), a pharmacopoeial impurity reference standard (molecular formula C29H50O3, MW 446.71 g/mol) used for the identification and quantification of trace impurities in APIs.
Structurally, Tocopherol Impurity 30 (C29H50O3) contains a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 446.71 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.
