2-n-Propyl-4-oxopentanoic acid

Description

2-n-Propyl-4-oxopentanoic acid is a metabolite of valproic acid. Valproic acid (VPA) is a chemical compound and an acid that has found clinical use as an anticonvulsant and mood-stabilizing drug, primarily in the treatment of epilepsy, bipolar disorder, and, less commonly, major depression. It is also used to treat migraine headaches and schizophrenia. VPA is a liquid at room temperature, but it can be reacted with a base such as sodium hydroxide to form the salt sodium valproate, which is a solid. (Wikipedia)
