Trospium Impurity 9 CAS CATO-C4X-20389 chemical structure

Description

Trospium Impurity 9 (CAS CATO-C4X-20389) is a certified pharmaceutical impurity reference standard with the molecular formula C21H22N2O4 and a molecular weight of 366.41 g/mol.

Based on its molecular formula C21H22N2O4, Trospium Impurity 9 contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 366.41 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

CATO manufactures Trospium Impurity 9 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.
