Chemical Structure

Granisetron EP Impurity E CAS 76272-56-5 chemical structure

Description

Based on its molecular formula C9H18N2, Granisetron EP Impurity E contains a nitrile group; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 154.25 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.

As a process- or degradation-related impurity, Granisetron EP Impurity E (CAS 76272-56-5, C9H18N2) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

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), Granisetron EP Impurity E 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.
