5-ho-dipt 5-ho-dipt 5-ho-dipt (5-hydroxy-n,n-di-iso-propyltryptamine) is a tryptamine derivative which acts as a serotonin receptor agonist. it is primarily known as a metabolite of the better known psychoactive drug 5-meo-dipt, but 5-ho-dipt has also rarely been encountered as a designer drug in its own right. tests in vitro show 5-ho-dipt to have high 5-ht2a affinity and good selectivity over 5-ht1a, while being more lipophilic than the related drug bufotenine (5-ho-dmt), which produces mainly peripheral effects. 5-ho-diptidentifiers iupac name 3-(2-(diisopropylamino)ethyl)-1h-indol-5-ol cas number36288-76-3 npubchem cid71360804chemspider29358411uniig7i3obf3xmcomptox dashboard (epa)dtxsid80784573 chemical and physical dataformulac16h24n2omolar mass260.381 g·mol−13d model (jsmol)interactive image smiles cc(c)n(ccc1=cnc2=c1c=c(c=c2)o)c(c)c inchi inchi=1s/c16h24n2o/c1-11(2)18(12(3)4)8-7-13-10-17-16-6-5-14(19)9-15(13)16/h5-6,9-12,17,19h,7-8h2,1-4h3key:hwolntjliuheog-uhfffaoysa-n
