Pimavanserin impurity 54 CAS 4734-09-2 chemical structure

Description

As a certified reference material (CRM), Pimavanserin impurity 54 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 Pimavanserin impurity 54 (CAS 4734-09-2), a pharmacopoeial impurity reference standard (molecular formula C11H17NO, MW 179.26 g/mol) used for the identification and quantification of trace impurities in APIs.

The molecular framework of Pimavanserin impurity 54 (C11H17NO) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
