[{"from": "human", "value": "Could you give me a brief overview of this molecule? [C][O][C][=Branch1][C][=O][/C][=C][\\C][=Branch1][C][=O][O][C]"}, {"from": "gpt", "value": "The molecule is a maleate ester resulting from the formal condensation of both carboxy groups of maleic acid with methanol. It is commonly used as a dienophile for Diels-Alder-type cycloaddition reactions in organic synthesis. It is a maleate ester, a diester and a methyl ester. It is functionally related to a methanol."}]
