Metabolite Identification
Common Name2-Heptyl acetate
Description2-heptyl acetate is a member of the class of compounds known as carboxylic acid esters. Carboxylic acid esters are carboxylic acid derivatives in which the carbon atom from the carbonyl group is attached to an alkyl or an aryl moiety through an oxygen atom (forming an ester group). 2-heptyl acetate is practically insoluble (in water) and an extremely weak basic (essentially neutral) compound (based on its pKa). 2-heptyl acetate can be found in cloves, which makes 2-heptyl acetate a potential biomarker for the consumption of this food product. Heptyl acetate is used as a fruit essence flavoring in foods and as a scent in perfumes. It has a woody, fruity, rumlike odor and a spicy, floral taste with a soapy, fatty texture .
