Chemical Structure

Ertapenem Impurity N4 CAS 444057-64-1 chemical structure

Description

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 process- or degradation-related impurity, Ertapenem Impurity N4 (CAS 444057-64-1, N/A) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Ertapenem Impurity N4 is supplied as a fully characterized reference material; its structural identity, assigned purity, and stability data are documented in the batch-specific Certificate of Analysis (COA).

As a certified reference material (CRM), Ertapenem Impurity N4 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.
