Tiotropium Bromide Impurity 31 CAS 54725-49-4

Description

Compared with other compounds in its class, the molecular weight of 139.19 g/mol gives Tiotropium Bromide Impurity 31 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

As a process- or degradation-related impurity, Tiotropium Bromide Impurity 31 (CAS 54725-49-4, C8H13NO) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Based on its molecular formula C8H13NO, Tiotropium Bromide Impurity 31 contains an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 139.19 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.

As a certified reference material (CRM), Tiotropium Bromide Impurity 31 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.
