Phenylpiracetam hydrazide, also known as fonturacetam hydrazide,[1] is a racetam that is a derivative of phenylpiracetam in which the amide group is replaced with a hydrazide group. It was first reported by a Russian research group in 1980 as part of a series of chemical compounds investigated as anticonvulsants.[2] In an electroshock test it was found to have an ED50 of 310 mg/kg.[2]

Sale on the internet

All piracetam derivatives are not permitted to be sold as dietary supplements in the United States.[3] However, because they lack scheduling, piracetam derivatives like phenylpiracetam hydrazide are sold over the clear net accompanied by indications stating that the compound is "not for human consumption".[4]
