Cannabis Compound Identification
Common Name5-ethylpyrazole
Description5-Ethylpyrazole also known as 5-ethyl-1H-pyrazole, an alkylpyrazole- an ethylated derivative of pyrazole, is one of several isomeric derivatives of pyrazole that contain an ethyl substituent. It belongs to the class of organic compounds known as pyrazoles. Pyrazoles are compounds containing a pyrazole ring, which is a five-member aromatic ring with two nitrogen atoms (at positions 1 and 2) and three carbon atoms. 5-Ethylpyrazole is a strong basic compound. 5-Ethylpyrazole is formed during the combustion of cannabis and is therefore a constituent of cannabis smoke ( Ref:DOI ).
