[{"from": "human", "value": "Describe this molecule. [C][C][C][S][=Branch1][C][=O][=Branch1][C][=O][C][Ring1][#Branch1]"}, {"from": "gpt", "value": "The molecule is a member of the class of tetrahydrothiophenes that is tetrahydrothiophene in which the sulfur has been oxidised to give the corresponding sulfone. A colourless, high-boiling (285\u2103) liquid that is miscible with both water and hydrocarbons, it is used as an industrial solvent, particularly for the purification of hydrocarbon mixtures by liquid-vapour extraction. It has a role as a polar aprotic solvent. It is a sulfone and a member of tetrahydrothiophenes. It derives from a hydride of a tetrahydrothiophene."}]
