Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 319.35 g/mol gives Bisacodyl EP Impurity C distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Bisacodyl EP Impurity C (CAS 72901-16-7), a pharmacopoeial impurity reference standard (molecular formula C20H17NO3, MW 319.35 g/mol) used for the identification and quantification of trace impurities in APIs.
The molecular framework of Bisacodyl EP Impurity C (C20H17NO3) 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 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.
As a certified reference material (CRM), Bisacodyl EP Impurity C 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.
