The molecule is an organic anion obtained by deprotonation of the 5 and 7 positions of cyanidin 3-O-(2-O-beta-D-glucuronosyl)-beta-D-glucoside. It is the major microspecies at pH 7.3 (according to Marvin v 6.2.0.). It derives from a cyanidin cation. It is a conjugate base of a cyanidin 3-O-(2-O-beta-D-glucuronosyl)-beta-D-glucoside betaine.
