Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 366.30 g/mol gives Trospium Impurity 11 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Trospium Impurity 11 (CAS CATO-C4X-203811) is a certified pharmaceutical impurity reference standard with the molecular formula C18H24NO2Br and a molecular weight of 366.30 g/mol.
The molecular framework of Trospium Impurity 11 (C18H24NO2Br) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution. 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
CATO manufactures Trospium Impurity 11 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.
