Determination of the pKa for caffeic acid in mixed solvent using the net analyte signal method and ab initio theory

Determination of the pKa for caffeic acid in mixed solvent using the net analyte signal method and ab initio theory

Due to the biological effects of phenolic acid components, polyphenol-rich foods are a significant part of human and animal diets. In this study, the acidity constants of caffeic acid (3,4-dihydroxycinnamic acid) in binary mixtures of ethanol–water were determined spectrophotometrically using the in...
