Amphetamines are chemical compounds characterized by an α-methylphenethylamine base structure. D-amphetamine is a stimulant that binds the norepinephrine and dopamine transporters (EC50s = 7.1 and 24.8 nM, respectively). 2-Amino-1-phenylbutane is an amphetamine characterized by having an ethyl group in the alpha position. It has emerged as a potential recreational drug. This product is a mixture of the D and L isomers. The D isomer of this compound partially substitutes for D-amphetamine in an animal discrimination analysis, suggesting that it weakly mimicks the signaling and stimulant properties of D-amphetamine. This product is intended for forensic and research applications.
