Specification: |
A monoester derivative of of 5-(Methoxycarbonyl)thiophene-2-carboxylic acid (CAS NO.50340-79-9) , the carboxylic acid and the carboxylic acid ester groups are approximately coplanar with thiophene ring, making a dihedral angle of 3.1 (4) and 3.6 (4)°, respectively. In the crystal structure, molecules are connected by classical intermolecular O-HO hydrogen bonds, forming centrosymmetric dimers.
