3,3,4-Trimethyl-1-(1-pentylindol-3-yl)pent-4-en-1-one

BeschreibungUR-144 is a synthetic cannabinoid (CB) analog of JWH 018 in which the naphthalene ring is substituted with a tetramethylcyclopropyl group. This substitution results in a compound which is a potent agonist for the peripheral CB2 receptor. UR-144 Degradant is a common impurity observed during GC-MS analysis of samples containing UR-144. The opened ring of the degradant is presumed to be produced during heating of UR-144. This structure gives rise to a prominent fragment ion that is 15 amu greater than the base peak of UR-144. This pattern is consistent with McLafferty rearrangement of the degradant which does not occur with the parent compound.
