Chemical Structure

Bisacodyl Impurity 23 CAS CATO-C4X-203723 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 379.84 g/mol gives Bisacodyl Impurity 23 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Bisacodyl Impurity 23 (CAS CATO-C4X-203723), a pharmacopoeial impurity reference standard (molecular formula C22H18ClNO3, MW 379.84 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, Bisacodyl Impurity 23 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 379.84 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
