6-mapdb 6-mapdb 6-mapdb (1-(2,3-dihydrobenzofuran-6-yl)-n-methylpropan-2-amine) is a chemical compound which might be an entactogenic drug. it is structurally related to drugs like 6-apdb and 6-mapb, which have similar effects to mdma and have been used as recreational drugs. 6-mapdb has never been studied to determine its pharmacological activity, though it is the n-methyl derivative of 6-apdb which is known to be a selective serotonin releaser. 6-mapdblegal statuslegal status ca: schedule i de: npsg (industrial and scientific use only) uk: class b identifiers iupac name 1-(2,3-dihydro-1-benzofuran-6-yl)-n-methylpropan-2-amine cas number1354631-81-4pubchem cid112500534chemspider32078889unii1c25e596ygchemical and physical dataformulac12h17nomolar mass191.274 g·mol−13d model (jsmol)interactive image smiles cc(cc1=cc2=c(cco2)c=c1)nc inchi inchi=1s/c12h17no/c1-9(13-2)7-10-3-4-11-5-6-14-12(11)8-10/h3-4,8-9,13h,5-7h2,1-2h3key:zkmveorlsjxobd-uhfffaoysa-n legality 6-mapdb was banned in the uk in june 2013 as a temporary class drug along with 9 other related compounds, despite having never been sold as a street drug itself. this was due to concerns that it would have similar effects to drugs such as 6-apb that had been widely sold already, and 6-mapdb might therefore be likely to become used recreationally also, if it were not banned preemptively.
