3,4-Pyridinedicarboxylic acid Chemical Properties,Uses,Production

Chemical Properties

white to slightly beige fine crystalline powder

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.
