Oxcarbazepine EP Impurity A (Carbamazepine) CAS 298-46-4

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Oxcarbazepine EP Impurity A (Carbamazepine).

Oxcarbazepine EP Impurity A (Carbamazepine) (CAS 298-46-4) is a certified pharmaceutical impurity reference standard with the molecular formula C15H12N2O and a molecular weight of 236.27 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, Oxcarbazepine EP Impurity A (Carbamazepine) is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 236.27 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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), Oxcarbazepine EP Impurity A (Carbamazepine) 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.
