Chemical Structure

Carfilzomib Impurity 2 CAS 247068-84-4 chemical structure

Description

As a certified reference material (CRM), Carfilzomib Impurity 2 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.

As a process- or degradation-related impurity, Carfilzomib Impurity 2 (CAS 247068-84-4, C9H17NO2) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Carfilzomib Impurity 2 (C9H17NO2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. 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.

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.
