adamantyl-thpinaca adamantyl-thpinaca adamantyl-thpinaca (athpinaca, ad-thpinaca) is an indazole-based synthetic cannabinoid, which was first reported to europol in slovenia in january 2015. it is known as both the 1-adamantyl and 2-adamantyl isomers (sgt-40 and sgt-194 respectively), which can be distinguished by gc-ei-ms. it is banned in sweden and russia. both the 1-adamantyl and 2-adamantyl isomers are specifically listed as illegal drugs in japan. 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 adamantyl-thpinaca may also release amantadine. adamantyl-thpinacalegal statuslegal status ca: schedule ii de: npsg (industrial and scientific use only) uk: class b identifiers iupac name n-(2-adamantyl)-1-(tetrahydropyran-4-ylmethyl)indazole-3-carboxamide cas number2365471-86-7 y 1400742-48-4 (1-adamantyl isomer)pubchem cid123132009chemspider58858889unii7i4laf1r3ycomptox dashboard (epa)dtxsid101009995 chemical and physical dataformulac24h31n3o2molar mass393.531 g·mol−13d model (jsmol)interactive image smiles c12c(c3cc(cc(c1)c3)c2)nc(=o)c2=nn(c3=cc=cc=c23)cc2ccocc2 inchi inchi=1/c24h31n3o2/c28-24(25-22-18-10-16-9-17(12-18)13-19(22)11-16)23-20-3-1-2-4-21(20)27(26-23)14-15-5-7-29-8-6-15/h1-4,15-19,22h,5-14h2,(h,25,28)/f/h25hkey:xfzlbndgzvrjnj-uhfffaoysa-n
