Chemical Information
FooDB NamePentyl pentanoate
DescriptionPentyl pentanoate, also known as pentyl pentanoic acid, is a member of the class of compounds known as fatty acid esters. Fatty acid esters are carboxylic ester derivatives of a fatty acid. Pentyl pentanoate is practically insoluble (in water) and an extremely weak basic (essentially neutral) compound (based on its pKa). Pentyl pentanoate is an apple, fruity, and ripe tasting compound found in peppermint, which makes pentyl pentanoate a potential biomarker for the consumption of this food product. Pentyl pentanoate (C4H9COOC5H11) is an ester used in dilute solution to replicate the scent or flavour of apple, and sometimes pineapple. It is referred to as pentyl valerate or amyl pentanoate using classical nomenclature. it can be used for a variety of chemical uses, such as in the production of flavoured products, like sweets .
