Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of anticonvulsant drugs like phenytoin and other hydantoin derivatives. It serves as a building block in organic synthesis due to its reactive cyclic urea structure, enabling the formation of various heterocyclic compounds. Commonly employed in the development of agrochemicals and specialty polymers, where it contributes to the stability and functionality of the final products. Its derivatives are also explored in medicinal chemistry for antimicrobial and anti-inflammatory agents.
