General description

5-(4-Hydroxyphenyl)-5-phenylhydantoin is the major metabolite of phenytoin.

Application

5-(4-Hydroxyphenyl)-5-phenylhydantoin was used in enantiomeric separation of chiral pharmaceuticals using a teicoplanin chiral stationary phase by aqueous and non-aqueous packed capillary electrochromatography. It was used as internal standard in determination of phenylbutazone and its metabolite oxyphenbutazone in human plasma by GLC.
Reactant for activation of hydroxylated metabolites of carbamazepine and phenytoin

Used in studies investigating
Transport across the human placenta barrier
Effects on cellular glucose transport

Enantiomeric separation of chiral pharmaceuticals is carried out in aqueous and non-aqueous packed capillary electrochromatography (CEC) using a teicoplanin chiral stationary phase (CSP). Capillaries were slurry packed with 5 microm 100-A porous silica particles modified with teicoplanin and initially evaluated
