The molecule is an oxo monocarboxylic acid anion that is the a dianion resulting from the carboxy group and the beta-keto-enol group of 3-farnesyl-6-hydroxy-2,3,5-trimethyl-4-oxocyclohexa-1,5-diene-1-carboxylic acid; major species at pH 7.3. It is a conjugate base of a (3R)-farnesyl-6-hydroxy-2,3,5-trimethyl-4-oxocyclohexa-1,5-diene-1-carboxylic acid.
(3R)-2,3,5-trimethyl-6-oxido-4-oxo-3-[(2E,6E)-3,7,11-trimethyldodeca-2,6,10-trienyl]cyclohexa-1,5-diene-1-carboxylate
