Oxcarbazepine: reference standards and impurities

Oxcarbazepine is an antiepileptic drug, a keto derivative of carbamazepine. In the body it is almost completely converted to the active metabolite, the 10-monohydroxy derivative (licarbazepine), so analytical work with oxcarbazepine needs standards for both the substance and the metabolite.
