ChEBI: Cinchomeronic acid is a pyridinedicarboxylic acid. It is a conjugate acid of a cinchomeronate(1-). | [Purification Methods]
Crystallise the acid from H2O or dilute aqueous HCl. It has also been purified via the dimethyl ester which is distilled (b 95-100o/1.5mm) and hydrolysed with 3.5N HCl, evaporated and recrystallised.
