Chemical Information
FooDB NameTrimethylthiazole
DescriptionTrimethylthiazole, also known as fema 3325, belongs to the class of organic compounds known as 2,4,5-trisubstituted thiazoles. 2,4,5-trisubstituted thiazoles are compounds containing a thiazole ring substituted at positions 2, 4 and 5 only. Trimethylthiazole is a strong basic compound (based on its pKa). Trimethylthiazole is a chocolate, cocoa, and coffee tasting compound. Trimethylthiazole is found, on average, in the highest concentration within kohlrabis. Trimethylthiazole has also been detected, but not quantified in, several different foods, such as coffee and coffee products, mung beans, potato, soy beans, and tea. This could make trimethylthiazole a potential biomarker for the consumption of these foods.
