Chemical Structure

Carfilzomib Impurity 64 CAS 1541171-68-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 855.03 g/mol gives Carfilzomib Impurity 64 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

As a process- or degradation-related impurity, Carfilzomib Impurity 64 (CAS 1541171-68-9, C46H62N8O8) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Based on its molecular formula C46H62N8O8, Carfilzomib Impurity 64 contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 855.03 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.

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.
