Chemical Properties

White solid

Structure and conformation

Thiophene-2,5-dicarboxylic acid monomethyl ester (TDCEM) has been shown to form dimers in solution. The crystal structure of TDCEM has been determined and found to be centrosymmetric with hydrogen bonds between the carbonyl oxygen atoms and the methyl groups on either side, as well as dihedral angles for the two methyl groups.
