Those are aromatic compounds containing Aromatic compounds containing a cinnamic acid moiety (or a derivative thereof) hydroxylated at the C2 (ortho-), C3 (meta-), or C4 (para-) carbon atom of the benzene ring. Caffeic acid ethyl ester is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Caffeic acid ethyl ester can be found in eggplant and vinegar, which makes caffeic acid ethyl ester a potential biomarker for the consumption of these food products. Ethyl caffeate is an ester of an hydroxycinnamic acid, a naturally occurring organic compound .
