1-Benzylhydantoin is primarily utilized in the synthesis of various pharmaceutical compounds. It serves as a key intermediate in the production of anticonvulsant drugs, which are used to treat epilepsy and other seizure disorders. Additionally, it finds application in the development of other therapeutic agents due to its hydantoin ring structure, which is a common feature in many biologically active molecules. Its role in medicinal chemistry extends to the creation of compounds with potential anti-inflammatory and anti-cancer properties. Furthermore, it is employed in research settings for the study of enzyme inhibition and receptor binding, aiding in the discovery of new drug candidates.
