3,4-Dimethylbenzoic acid Usage And Synthesis

Chemical Properties	white to beige crystalline powder

Definition	ChEBI: A dimethylbenzoic acid in which the two methyl groups are located at positions 3 and 4.

Purification Methods	Crystallise it from EtOH or H2O (m 168-168.5o), and sublime it in vacuo. The phenyl ester has m 68o (from EtOH or pet ether) and b 155-157o/2mm. [Beilstein 9 II 353, 9 III 2441, 9 IV 1803.]
