| Common Name | 4-Methylthiazole |
|---|
| Description | 4-Methylthiazole, also known as fema 3716, belongs to the class of organic compounds known as thiazoles. These are heterocyclic compounds containing a five-member aromatic ring made up of one sulfur atom, one nitrogen, and three carbon atoms. 4-Methylthiazole is a green, nutty, and roasted meat tasting compound. 4-methylthiazole has been detected, but not quantified, in several different foods, such as cereals and cereal products, coffee and coffee products, crustaceans, green vegetables, and nuts. This could make 4-methylthiazole a potential biomarker for the consumption of these foods. 4-Methylthiazole has been linked to the inborn metabolic disorders including celiac disease. A 1,3-thiazole substituted by a methyl group at position 4. |
