Isopropylphenidate (also known as IPH and IPPD) is a piperidine based stimulant drug, closely related to methylphenidate, but with the methyl ester replaced by an isopropyl ester. It has similar effects to methylphenidate but with a longer duration of action,[1][2] and was banned in the UK as a Temporary Class Drug from April 2015 following its unapproved sale as a designer drug.[3]
