jwh-302 jwh-302 jwh-302 (1-pentyl-3-(3-methoxyphenylacetyl)indole) is an analgesic chemical from the phenylacetylindole family, which acts as a cannabinoid agonist with moderate affinity at both the cb1 and cb2 receptors. it is a positional isomer of the more common drug jwh-250, though it is slightly less potent with a ki of 17 nm at cb1, compared to 11 nm for jwh-250. because of their identical molecular weight and similar fragmentation patterns, jwh-302 and jwh-250 can be very difficult to distinguish by gc-ms testing. jwh-302legal statuslegal status us: schedule i identifiers iupac name 2-(3-methoxyphenyl)-1-(1-pentylindol-3-yl)ethanone cas number864445-45-4 npubchem cid11493740chemspider9668546 yuniidqf20nhw2mchemblchembl186674 ycomptox dashboard (epa)dtxsid60467554 chemical and physical dataformulac22h25no2molar mass335.447 g·mol−13d model (jsmol)interactive image smiles c2ccc(oc)cc2cc(=o)c(cn1ccccc)c3ccccc13 inchi inchi=1s/c22h25no2/c1-3-4-7-13-23-16-20(19-11-5-6-12-21(19)23)22(24)15-17-9-8-10-18(14-17)25-2/h5-6,8-12,14,16h,3-4,7,13,15h2,1-2h3 ykey:xzvywlvyuaqeim-uhfffaoysa-n y ny (what is this?)
