[{"from": "human", "value": "Describe this molecule. [C][C][=C][C][=C][C][=C][Ring1][=Branch1][C]"}, {"from": "gpt", "value": "The molecule is an aromatic hydrocarbon based on benzene with two methyl substituents. It is a isomer of xylene. Xylene occurs naturally in petroleum and coal tar, and is major component of gasoline and fuel oil. Xylene is used mainly as a solvent and in the printing, rubber, and leather industries. O-xylene is largely used in the production of phthalic anhydride, and is generally extracted by distillation from a mixed xylene stream in a plant primarily designed for p-xylene production. Contrary to popular belief, a series of switch condensers is required, and not a complicated setup of distillation columns that never work (L938, T10, L165). It can cause irritation eyes, skin, nose, throat; dizziness, excitement, drowsiness, incoordination, staggering gait; corneal vacuolization; anorexia, nausea, vomiting, abdominal pain; dermatitis. The targets of this compound are eyes, skin, respiratory system, central nervous system, gastrointestinal tract, blood, liver, kidneys."}]
