Chemical Structure

Ezetimibe Impurity 51 CAS 693-13-0 chemical structure

Description

Owing to a nitrile group, Ezetimibe Impurity 51 is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 126.20 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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, Ezetimibe Impurity 51 (CAS 693-13-0, C7H14N2) 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), Ezetimibe Impurity 51 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.
