Cannabis Compound Identification
Common Name2-Aminopurine
Description2-Aminopurine, also known as 9H-purin-2-amine, belongs to the class of organic compounds known as purines and purine derivatives. These are aromatic heterocyclic compounds containing a purine moiety, which is formed a pyrimidine-ring ring fused to an imidazole ring. The parent compound of the 2-Aminopurines, comprising a purine core carrying an amino substituent at the 2-position. 2-Aminopurine is one of several structural isomers of aminopurine wherein the amino group is substituted at different positions around the purine ring. It is a purine analog of guanine and adenine and is used as a fluorescent molecular marker in nucleic acid research (PMID: 11120885 ). 2-Aminopurine most commonly pairs with thymine as an adenine-analogue but can also pair with cytosine as a guanine-analogue (PMID: 3461441 ). 2-Aminopurine is a constituent of cannabis smoke and is formed during the combustion of cannabis ( Ref:DOI ).
