RTI‑111, also known as Dichloropane, is a synthetic chemical compound belonging to the phenyltropane class of stimulants. It is structurally related to cocaine and was originally developed during scientific research investigating how cocaine‑like molecules interact with monoamine transporters in the brain. The compound’s chemical name is methyl (1R,2S,3S,5S)-3-(3,4‑dichlorophenyl)-8‑azabicyclo[3.2.1]octane‑2‑carboxylate, and it has the molecular formula C15H17Cl2NO2.

In pharmacological studies, RTI‑111 acts as a serotonin‑norepinephrine‑dopamine reuptake inhibitor (SNDRI), meaning it influences neurotransmitter transport systems related to stimulation and reward pathways. Experimental research has shown that the compound can produce stimulant‑like effects and has a slower onset but longer duration of action compared with cocaine in certain animal studies.
