Chemical Information
FooDB Name2,4-Dihydroxybenzoic acid
Description2,4-Dihydroxybenzoic acid, also known as b-resorcylic acid or 4-hydroxysalicylic acid, belongs to the class of organic compounds known as hydroxybenzoic acid derivatives. Hydroxybenzoic acid derivatives are compounds containing a hydroxybenzoic acid (or a derivative), which is a benzene ring bearing a carboxyl and a hydroxyl groups. 2,4-Dihydroxybenzoic acid is an extremely weak basic (essentially neutral) compound (based on its pKa). 2,4-Dihydroxybenzoic acid is a mild and phenolic tasting compound. 2,4-Dihydroxybenzoic acid is found, on average, in the highest concentration within american cranberries and olives. 2,4-Dihydroxybenzoic acid has also been detected, but not quantified in, several different foods, such as alcoholic beverages, coffee and coffee products, fruits, and german camomiles. This could make 2,4-dihydroxybenzoic acid a potential biomarker for the consumption of these foods.
