Tiotropium Bromide EP Impurity C CAS 136310-95-7

Description

Compared with other compounds in its class, the molecular weight of 456.41 g/mol gives Tiotropium Bromide EP Impurity C distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

As a process- or degradation-related impurity, Tiotropium Bromide EP Impurity C (CAS 136310-95-7, C19H22NO3S2Br) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Tiotropium Bromide EP Impurity C (C19H22NO3S2Br) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point, 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. 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.

As a certified reference material (CRM), Tiotropium Bromide EP Impurity C 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.
