D-Vacciniin belongs to the class of organic compounds known as benzoic acid esters. These are ester derivatives of benzoic acid. D-Vacciniin exists as a solid, soluble (in water), and a very weakly acidic compound (based on its pKa). Outside of the human body, D-vacciniin can be found in fruits. This makes D-vacciniin a potential biomarker for the consumption of this food product.
