GENERAL DESCRIPTION AND APPLICATIONS

Hydantoin, also known as glycolyurea, is an imidazole analogue. It is a heterocyclic compound having two ketone groups in the five-membered ring structure composed of three carbon atoms and two nitrogen atoms at nonadjacent positions. It is a white crystalline compound; slightly soluble in water; melting at 222 C. Hydantoin and its derivatives are used in the preperation of textile softeners, lubricants, resins, and agrochemicals. They have bacteriostatic and bacteriacidal capabilities useful preservatives against bacteria and fungi. They have antibacterial, antifungal, antiprotozoal, and anthelmintic activity. They are used in manufacturing pharmaceuticals especially anticonvulsant drugs such as phenytoin, ethotoin, and methyphenytoin.
