5f-sdb-006 5f-sdb-006 5f-sdb-006 is a drug that acts as a potent agonist for the cannabinoid receptors, with an ec50 of 50 nm for human cb1 receptors, and 123 nm for human cb2 receptors. it was discovered during research into the related compound apica which had been sold illicitly as "2ne1". 5f-sdb-006 is the terminally fluorinated analog of sdb-006, just as sts-135 is the terminally fluorinated analog of apica. given the known metabolic liberation (and presence as an impurity) of amantadine in the related compound apinaca, it is suspected that metabolic hydrolysis of the amide group of 5f-sdb-006 may release benzylamine. 5f-sdb-006legal statuslegal status ca: schedule ii de: anlage ii (authorized trade only, not prescriptible) uk: class b identifiers iupac name n-benzyl-1-(5-fluoropentyl)-1h-indole-3-carboxamide cas number1776086-02-2pubchem cid91936847chemspider30646773unii4up4sxx8bwchemical and physical dataformulac21h23fn2omolar mass338.426 g·mol−13d model (jsmol)interactive image smiles fcccccn1c=c(c(ncc2=cc=cc=c2)=o)c3=c1c=cc=c3 inchi inchi=1s/c21h23fn2o/c22-13-7-2-8-14-24-16-19(18-11-5-6-12-20(18)24)21(25)23-15-17-9-3-1-4-10-17/h1,3-6,9-12,16h,2,7-8,13-15h2,(h,23,25)key:vflxawvawxhmfb-uhfffaoysa-n
