 Benzylbutylbarbiturate

Benzylbutylbarbiturate (5-benzyl-5-"n"-butylbarbituric acid) is a rare example of a barbiturate designer drug, possibly the only such compound encountered in recent years.It was confiscated by police in Japan in 2000, and presumably was a product of clandestine manufacture as this compound has never previously been sold as a legal pharmaceutical.
