Cinnamaldehydes are organic aromatic compounds containing a cinnamlaldehyde moiety, consisting of a benzene and an aldehyde group to form 3-phenylprop-2-enal (e)-3-(2-hydroxyphenyl)-2-propenal is slightly soluble (in water) and a very weakly acidic compound (based on its pKa). (e)-3-(2-hydroxyphenyl)-2-propenal can be found in herbs and spices, which makes (e)-3-(2-hydroxyphenyl)-2-propenal a potential biomarker for the consumption of this food product.
