Task: Please create a text description for a molecule.
Molecule SMILES: O=C(O)/C=C1/C=C(Cl)C(=O)O1
Constraint: Answer the question with full sentences.
Result: The molecule is the trans-isomer of 2-chloro-4-carboxymethylenebut-2-en-1,4-olide. It is a 2-chloro-4-carboxymethylenebut-2-en-1,4-olide and a chlorodienelactone. It derives from a trans-4-carboxymethylenebut-2-en-4-olide. It is a conjugate acid of a trans-2-chloro-4-carboxylatomethylenebut-2-en-1,4-olide(1-).
