2-Aminoindane (2-AI) is a research chemical with applications in neurologic disorders and psychotherapy that has also been sold as a designer drug.[1] It acts as a selective substrate for NET and DAT.[2][3]

Therapeutic and illicit uses

Synthetic aminoindanes were originally developed in the context of anti-Parkinsonian drugs as a metabolite of rasagiline and as a tool to be used in psychotherapy. Deaths related to their toxic effects have been observed both in the laboratory in animal studies and in clinical encounters.[4] 2-AI is a rigid analogue of amphetamine and partially substitutes for it in rat discrimination tests.[5]

Legal status

Sweden's public health agency suggested classifying 2-AI as a hazardous substance, on June 24, 2019.[6]

Chemical derivatives

There are a number of derivatives of 2-aminoindane and its positional isomer 1-aminoindane exist, including:



As of October 2015 2-AI is a controlled substance in China.[7]

United States

2-Aminoindane is not scheduled at the federal level in the United States,[8] but may be considered an analog of amphetamine, in which case purchase, sale, or possession could be prosecuted under the Federal Analog Act.
