Common Name2-Methyl-1H-imidazole
Description2-Methylimidazole, belongs to the class of organic compounds known as imidazoles. Imidazoles are compounds containing an imidazole ring, which is an aromatic five-membered ring, that includes two nitrogen atoms at positions 1 and 3, and three carbon atoms. 2-MethylImidazole has the chemical formula CH3C3H2N2H and is a methylated derivative of Imidazole on which a methyl group has been added at position C-2. It is a white or colorless solid that is highly soluble in polar organic solvents and water. It is a precursor to a range of drugs and is a ligand in coordination chemistry. 2-Methylimidazole is prepared by condensation of glyoxal, ammonia, and acetaldehyde, through the Radziszewski reaction. 2-Methylimidazole is a sterically hindered imidazole that is used to simulate the coordination of histidine to heme complexes. It can be deprotonated to make imidazolate-based coordination polymers. 2-Methylimidazole is a precursor to several members of the nitroimidazole antibiotics that are used to combat anaerobic bacterial and parasitic infections. 2-methylimidazole has been found in the volatile fraction of Cannabis sativa (PMID: 26657499 ) and is likely a component of marijuana smoke ( Ref:DOI ).
