Cannabis Compound Identification
Common Name7,8-Benzoquinoline
Description7,8-Benzoquinoline or Benzo[h]quinoline also known as Benzoquinoline is a benzene derivative of quinoline in which the benzene group is fused to the C-7 and C-8 of quinoline. It belongs to the class of organic compounds known as quinolines and derivatives. Quinolines and derivatives are compounds containing a quinoline moiety, which consists of a benzene ring fused to a pyrimidine ring to form benzo[b]azabenzene. 7,8-Benzoquinoline exists as an off-white to brown crystalline powder. When heated to decomposition it emits toxic fumes. 7,8-Benzoquinoline causes skin and respiratory irritation and is known to cause serious eye irritation. Studies on rats have shown that 7,8-Benzoquinoline is able to induce both phase I (Cyp1A) and phase II (UDP-glucuronosyltransferase) activity towards certain drugs and therefore could function as a chemoprotective agent (PMID: 9176741 ). 7,8-Benzoquinoline is a constituent of marijuana (cannabis) smoke and is formed during the combustion of cannabis ( Ref:DOI ).
