Chemical Structure

Penehyclidine Impurity 6 (Mixture of Diastereomers) CAS 2564756-90-5 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 331.45 g/mol gives Penehyclidine Impurity 6 (Mixture of Diastereomers) distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

As a process- or degradation-related impurity, Penehyclidine Impurity 6 (Mixture of Diastereomers) (CAS 2564756-90-5, C20H29NO3) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

The molecular framework of Penehyclidine Impurity 6 (Mixture of Diastereomers) (C20H29NO3) is characterized by a steroid core, 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.

As a certified reference material (CRM), Penehyclidine Impurity 6 (Mixture of Diastereomers) 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.
