Natural Product Identification
Common Name2-Ethyl-4,5-dimethyloxazole
Description2-Ethyl-4,5-dimethyloxazole, also known as 4,5-dimethyl-2-ethyloxazole or fema 3672, belongs to the class of organic compounds known as 2,4,5-trisubstituted oxazoles. 2,4,5-Trisubstituted oxazoles are compounds containing an oxazole ring substituted at positions 2, 4 and 5 only. Oxazole is a five-membered aromatic heterocycle with one oxygen, one nitrogen, and three carbon atoms. Isomers include 1,2-oxazole and 1,3-oxazole. 2-Ethyl-4,5-dimethyloxazole is a moderately basic compound (based on its pKa). 2-Ethyl-4,5-dimethyloxazole is a creamy, earthy, and green tasting compound. Outside of the human body, 2-Ethyl-4,5-dimethyloxazole has been detected, but not quantified in, coffee and coffee products and potato. This could make 2-ethyl-4,5-dimethyloxazole a potential biomarker for the consumption of these foods.
