Cannabis Compound Identification
Common Name1,8-Naphthyridine
Description1,8-Naphthyridine or 1,8-diazanaphthalene also known as 1,8-pyridopyridine is one of the diazanaphthalene isomers, belongs to the class of organic compounds known as naphthyridines. Naphthyridines are compounds containing a naphthyridine moiety, a naphthalene in which a carbon atom has been replaced by a nitrogen in each of the two rings. The naphthyridine skeleton can also be described as an assembly two fused pyridine rings, which do not share their nitrogen atom. A naphthyridine in which the nitrogens are situated at positions 1 and 8. 1,8-Naphthyridine is a stongly basic compound (based on its pKa). Diazanaphthalene isomers have different structure based on their nitrogen positions while the skeleton is same for all isomers. 1,8-Naphthyridine, 1,6-Naphthyridine and 1,5-Naphthyridine are some of its isomers. 1,8-Naphthyridine is the most well-studied of the six isomeric naphthyridines. 1,8-Naphthyridine is formed during the combustion of cannabis and is therefore a constituent of cannabis smoke ( Ref:DOI ).
