Propylphenidine

Not to be confused with propylphenidate.

Propylphenidine is a compound which has been sold as a designer drug, first identified in Australia in 2023. It is unclear what kind of activity it has, as it is claimed to be a stimulant in a patent along with related compounds such as phenylpropylaminopentane, but other structurally similar compounds such as ephenidine and isophenidine are dissociative anesthetic drugs, so it may produce either kind of activity or perhaps a mixture of both.^[1][2][3]
