[{"from": "human", "value": "Provide a description of this molecule. [C][C][=C][C][=C][Branch1][Branch1][C][=C][Ring1][=Branch1][C][=C]"}, {"from": "gpt", "value": "The molecule appears as a clear colorless liquid with an aromatic odor. Usually shipped with an inhibitor such as tert-butyl catechol added May polymerize if contaminated or subjected to heat. If polymerization takes place inside a closed container, the container may rupture violently. Vapors irritate the mucous membranes. Less dense than water and insoluble in water. Hence floats on water. Used in making plastics, especially as a monomer for polyesters."}]
