||
| Hydantoin derived from imidazole is one of a class of organic heterocyclic compounds of five-membered ring structure composed of three carbon atoms and two nitrogen atoms at nonadjacent positions with dione form. It is a white crystalline compound; slightly soluble in water; melting at 222 C. Hydantoin and its derivatives are is used in textile softeners and lubricants.
