7-f-5-meo-met 7-f-5-meo-met 7-f-5-meo-met (5-meo-7-f-met, 5-methoxy-7-fluoro-n-methyl-n-ethyltryptamine) is a tryptamine derivative which acts as a serotonin receptor agonist selective for the 5-ht2 subtypes, with a pec50 of 8.71 at 5-ht2a, vs 8.25 at 5-ht2b and 7.69 at 5-ht2c. in animal tests it produced the most potent head-twitch response of a range of related fluorinated tryptamine derivatives tested, though still with slightly lower potency than psilocybin. 5-meo-7-f-metidentifiers iupac name n-ethyl-2-(7-fluoro-5-methoxy-1h-indol-3-yl)-n-methylethanamine pubchem cid166157921chemical and physical dataformulac14h19fn2omolar mass250.317 g·mol−13d model (jsmol)interactive image smiles ccn(c)ccc1=cnc2=c1c=c(c=c2f)oc inchi inchi=1s/c14h19fn2o/c1-4-17(2)6-5-10-9-16-14-12(10)7-11(18-3)8-13(14)15/h7-9,16h,4-6h2,1-3h3key:ikykxfmgtkylau-uhfffaoysa-n
