Methyl 2,6-dicarboxybenzoate.
Regioselective methylation of hemimellitic acid in basic MeOH yields the title 2-methyl ester, C(10)H(8)O(6), of the parent acid. The asymmetric unit contains one complete molecule, which packs with the methyl ester groups lying between zigzag chains produced by hydrogen bonding, utilizing the head-to-tail carboxylic acid-acid dimer motif.
