Propylphenidate (also known as PPH) is a piperidine based stimulant drug, closely related to methylphenidate, but with the methyl ester replaced by an propyl ester. It was banned in the UK as a Temporary Class Drug from April 2015 following its unapproved sale as a designer drug.[1] Propylphenidate can be synthesised from methylphenidate.[2]
