3,4-Dihydroxyphenylacetic acid

N. Okabe and H. Kyoyama

Abstract: In the title compound, C₈H₈O₄, the acetic acid side chain adopts a roughly perpendicular orientation with respect to the phenyl ring. Hydrogen bonding between carboxyl groups results in the formation of a centrosymmetric dimer. An intramolecular hydrogen bond is formed in the catechol part of the molecule. Molecules are linked together through hydrogen bonds between hydroxyl and carboxylic acid O atoms.
