4-methylimidazole (4-MEI) is a compound used to make certain pharmaceuticals, photographic chemicals, dyes and pigments, cleaning and agricultural chemicals, and rubber products. 4-MEI is formed during the production of certain caramel coloring agents used in many food and drink products. It may also be formed during the cooking, roasting, or other processing of some foods and beverages. ... Studies published in 2007 by the [U.S.] federal government’s National Toxicology Program showed that long-term exposure to 4-MEI resulted in increases in lung cancer in male and female mice. These findings were the basis for the addition of 4-MEI to California’s Proposition 65 list of carcinogens.  6, record 2, English, - 4%2Dmethylimidazole

... Since imidazole also exists in tautomeric forms, either of the nitrogen atoms can bear the hydrogen atom, the two nitrogens become indistinguishable and the numbering becomes rather complex for mono-substituted imidazoles. As a consequence of this, 4-methylimidazole is identical with 5-methylimidazole and, depending on the position of the imino hydrogen, such a compound may be designated either 4- or 5-methylimidazole. As only one substance that may be a single tautomer or an equilibrium mixture is known, it would be incorrect to call it eithier 4- or 5-methylimidazole. Such a compound is instead designated as 4(5)-methylimidazole.  8, record 2, English, - 4%2Dmethylimidazole
