Rac Mephenytoin-d3 is a deuterated form of racemic mephenytoin, an anticonvulsant used in the treatment of epilepsy. The “d3” designation indicates the presence of three deuterium atoms, which replace hydrogen atoms in the molecule. This deuterated analog is used as a stable internal standard in mass spectrometry for precise quantification of mephenytoin levels in biological and pharmaceutical studies. Mephenytoin functions by stabilizing neuronal membranes and inhibiting abnormal electrical activity in the brain. The deuterated form facilitates accurate pharmacokinetic and metabolic studies of mephenytoin, aiding in its therapeutic monitoring and drug development.
