Penehyclidine Impurity 28 CAS 3731-38-2 chemical structure

Description

As a certified reference material (CRM), Penehyclidine Impurity 28 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 Penehyclidine Impurity 28 (CAS 3731-38-2), a pharmacopoeial impurity reference standard (molecular formula C7H11NO, MW 125.17 g/mol) used for the identification and quantification of trace impurities in APIs.

The molecular framework of Penehyclidine Impurity 28 (C7H11NO) is characterized by an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
