1,3-Benzodioxolyl-N-methylbutanamine (N-methyl-1,3-benzodioxolylbutanamine, MBDB) is an entactogen of the phenethylamine chemical class. It is known by the street names Eden and Methyl-J. MBDB is a closely related chemical analogue of MDMA, with the only difference between the two molecules being an ethyl group instead of a methyl group attached to the alpha carbon. It has IC₅₀ values of 784 nM against 5-HT, 7825 nM against dopamine, and 1233 nM against norepinephrine. Its metabolism has been described in scientific literature.
