Used as a starting material in the synthesis of bioactive compounds, particularly in pharmaceutical research for developing anticonvulsant drugs and agents acting on the central nervous system. It is structurally related to phenytoin and may leverage similar mechanisms to inhibit voltage-dependent sodium channels, potentially stabilizing neuronal membranes and reducing excessive electrical activity in the brain. Additionally, it is employed in research to modify the hydantoin structure, a key scaffold in various active substances, which can be further developed into compounds with antimicrobial or antioxidant properties.
