Chemical Structure

Trospium Impurity 13 CAS CATO-C4X-203813 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Trospium Impurity 13.

CATO supplies Trospium Impurity 13 (CAS CATO-C4X-203813), a pharmacopoeial impurity reference standard (molecular formula C18H24NO2Cl, MW 321.84 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C18H24NO2Cl, Trospium Impurity 13 contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 321.84 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

As a certified reference material (CRM), Trospium Impurity 13 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.
