Palbociclib Impurity 33 CAS 1651214-74-2

Description

As a certified reference material (CRM), Palbociclib Impurity 33 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 Palbociclib Impurity 33 (CAS 1651214-74-2), a pharmacopoeial impurity reference standard (molecular formula C29H37N7O4, MW 547.65 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Palbociclib Impurity 33 (C29H37N7O4) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 15.0, corresponding to approximately 15 ring(s) or double-bond equivalent(s). With a molecular weight of 547.65 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
