Oxcarbazepine EP Impurity H CAS 4698-11-7 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 223.27 g/mol gives Oxcarbazepine EP Impurity H distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Oxcarbazepine EP Impurity H (CAS 4698-11-7) is a certified pharmaceutical impurity reference standard with the molecular formula C15H13NO and a molecular weight of 223.27 g/mol.

Oxcarbazepine EP Impurity H (C15H13NO) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; 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.

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.

As a certified reference material (CRM), Oxcarbazepine EP Impurity H 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.
