Chemical Information
FooDB Name4-Methyl-5-vinylthiazole
Description4-Methyl-5-vinylthiazole, also known as 5-ethenyl-4-methyl-thiazole or fema 3313, belongs to the class of organic compounds known as 4,5-disubstituted thiazoles. 4,5-disubstituted thiazoles are compounds containing a thiazole ring substituted at positions 4 and 5 only. 4-Methyl-5-vinylthiazole is a moderately basic compound (based on its pKa). 4-Methyl-5-vinylthiazole is a cocoa, musty, and nutty tasting compound. 4-Methyl-5-vinylthiazole is found, on average, in the highest concentration within soft-necked garlics. 4-Methyl-5-vinylthiazole has also been detected, but not quantified in, several different foods, such as alcoholic beverages, cocoa and cocoa products, fruits, nuts, and onion-family vegetables. This could make 4-methyl-5-vinylthiazole a potential biomarker for the consumption of these foods.
