[{"from": "human", "value": "Could you provide a description of this molecule? [C][C][Branch1][Ring2][O][Ring1][Ring1][C][=C][C][=C][C][=C][Ring1][=Branch1]"}, {"from": "gpt", "value": "The molecule is used as a reactive plasticizer or diluent for epoxy resins and in the production of phenethyl alcohol and styrene glycol and its derivatives. Acute (short-term) exposure to styrene oxide causes skin and eye irritation in humans. Corneal injury, liver, and neurological effects have been reported in acutely exposed animals. No information is available on the chronic (long-term), reproductive, developmental, or carcinogenic effects of styrene oxide in humans. Maternal toxicity and increased fetal mortality have been observed in rats and rabbits exposed to styrene oxide by inhalation. Several studies have reported an increased incidence of forestomach tumors in rats and mice exposed via gavage (experimentally placing the chemical in the stomach). The International Agency for Research on Cancer (IARC) has classified styrene oxide as a Group 2A, a probable human carcinogen."}]
