Chemical Structure
Description
As a process- or degradation-related impurity, Hydantoin Impurity 3 (CAS 138849-22-6, N/A) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
Hydantoin Impurity 3 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).
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), Hydantoin Impurity 3 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.
