It was introduced approximately 10 years after phenytoin, in the late 1940s. The significant metabolite of mephenytoin is nirvanol (5-ethyl-5-phenylhydantoin), which was the first hydantoin (briefly used as a hypnotic). However, nirvanol is quite toxic and mephenytoin was only considered after other less toxic anticonvulsants had failed. It can cause potentially fatal blood dyscrasia in 1% of patients. Mephenytoin is no longer available in the US or the UK. It is still studied largely because of its interesting hydroxylation polymorphism.Product Details:Name: MephenytoinCAS#: 50-12-4 (racemic)Chemical Formula: C12H14N2O2Exact Mass: 218.10553Molecular Weight: 218.25Elemental Analysis: C, 66.04; H, 6.47; N, 12.84; O, 14.66Specification:Synonym: Mephenytoin; Methoin; Mesantoin; Phenantoin; Methylphenetoin; Insulton.IUPAC/Chemical Name: 5-ethyl-3-methyl-5-phenylimidazolidine-2,4-dioneInChi Key: GMHKMTDVRCWUDX-UHFFFAOYSA-NInChi Code: InChI=1S/C12H14N2O2/c1-3-12(9-7-5-4-6-8-9)10(15)14(2)11(16)13-12/h4-8H,3H2,1-2H3,(H,13,16)SMILES Code: CCC1(C(=O)N(C(=O)N1)C)C2=CC=CC=C2Appearance: White powderPurity: >98% (or refer to the Certificate of Analysis)Shipping Condition: Shipped under ambient temperature as non-hazardous chemical.
