3-(p-Fluorobenzoyloxy)tropane

3β-(p-Fluorobenzoyloxy)tropane, (8-Methyl-8-azabicyclo[3.2.1]oct-3-yl 4-fluorobenzoic acid ester, 4-fluorotropacocaine, 3-Pseudotropyl-4-fluorobenzoate, 3-pseudotropyl-4-fluorobenzoate, pFBT) is a tropane derivative drug which acts as a local anaesthetic, having around 30% the stimulant potency of cocaine but around the same potency as a local anaesthetic. It has been investigated as a potential radiolabelled agent for studying receptor binding, but was not adopted for this application. The main application for fluorotropacocaine, however, has been as a designer drug analogue of cocaine, first detected by the EMCDDA in 2008, and subsequently sold as an ingredient of various "bath salt" powder products, usually mixed in combination with other stimulant drugs such as caffeine, dimethocaine, desoxypipradrol or substituted cathinone derivatives.
