In studies of the reactivity of oxygen heterocycles, it has been found that khelline gives a molar reacting ratio of 1:16 with vanadate in 2.5M sulphuric acid, the products being vanadium(IV), 2.3 furan dicarboxylic acid, formic acid, acetic acid and carbon dioxide. This reaction can be used for determination of khelline and also for preparation of 2,3-furan dicarboxylic acid.
