Hydantoin, or glycolylurea at Best Price, Supplier Manufacturer visakhapatnam India

Vizag chemical Hydantoin, or glycolylurea, is a heterocyclic organic compound with the formula CH2C(O)NHC(O)NH. It is a colorless solid that arises from the reaction of glycolic acid and urea. It is an oxidized derivative of imidazolidine. In a more general sense, hydantoins can refer to a groups and a class of compounds with the same ring structure as the parent. For example, phenytoin (mentioned below) has two phenyl groups substituted onto the number 5 carbon in a hydantoin molecule.

Uses and occurrence

Pharmaceuticals

The hydantoin group can be found in several medicinally important compounds. In pharmaceuticals, hydantoin derivatives form a class of anticonvulsants;[8] phenytoin and fosphenytoin both contain hydantoin moieties and are both used as anticonvulsants in the treatment of seizure disorders. The hydantoin derivative dantrolene is used as a muscle relaxant to treat malignant hyperthermia, neuroleptic malignant syndrome, spasticity, and ecstasy intoxication. Ropitoin is an example of an antiarrhythmic hydantoin.

Pesticides

The hydantoin derivative Imiprothrin is a pyrethroid insecticide. Iprodione is a popular fungicide containing the hydantoin group.

Synthesis of amino acids

Hydrolysis of hydantoins affords amino acids:

RCHC(O)NHC(O)NH + H2O → RCHC(NH2)CO2H + NH3
Hydantoin itself reacts with hot, dilute hydrochloric acid to give glycine. Methionine is produced industrially via the hydantoin obtained from methional.

Halogenation

Some N-halogenated derivatives of hydantoin are used as chlorinating or brominating agents in disinfectant/sanitizer or biocide products. The three major N-halogenated derivatives are dichlorodimethylhydantoin (DCDMH), bromochlorodimethylhydantoin (BCDMH), and dibromodimethylhydantoin (DBDMH). A mixed ethyl-methyl analogue, 1,3-dichloro-5-ethyl-5-methylimidazolidine-2,4-dione 

Iprodione is a popular fungicide containing the hydantoin group.
DNA oxidation to hydantoins after cell death
A high proportion of cytosine and thymine bases in DNA are oxidized to hydantoins over time after the death of an organism. Such modifications block DNA polymerases and thus prevents PCR from working. Such damage is a problem when dealing with ancient DNA samples.
