Bisacodyl Impurity 18 CAS 63019-58-9 chemical structure

Description

CATO manufactures Bisacodyl Impurity 18 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.

As a process- or degradation-related impurity, Bisacodyl Impurity 18 (CAS 63019-58-9, C19H17NO2) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Bisacodyl Impurity 18 (C19H17NO2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
