Oxcarbazepine Impurity 40 CAS 186694-45-1

Description

The occurrence of Oxcarbazepine Impurity 40 is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Oxcarbazepine Impurity 40 (CAS 186694-45-1) is a certified pharmaceutical impurity reference standard with the molecular formula C17H16N2O3 and a molecular weight of 296.32 g/mol.

Structurally, Oxcarbazepine Impurity 40 (C17H16N2O3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 296.32 g/mol, it falls into the medium-molecular-weight range. 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 Impurity 40 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.
