3,4-Pyridinedicarboxylic acid Chemical Properties,Usage,Production
Uses
Due to the electron-withdrawing effect of the nitrogen atom on the ring, electrophilic substitution reactions are generally difficult to occur. However, nucleophilic substitution reactions on the pyridine ring are relatively easy to occur. Taking advantage of this property, a variety of important pyridine compounds can be prepared from 3,4-pyridinedicarboxylic acid and its derivatives. Because they often have good biological activity, they are often used as important raw materials or intermediates for the synthesis of pharmaceuticals and pesticides, playing an important role in the synthesis of pyridine drugs.
Chemical Properties
white to slightly beige fine crystalline powder
Definition
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.
