[{"from": "human", "value": "Could you give me a brief overview of this molecule? [C][=C][C][=Branch1][#Branch1][=C][C][=C][Ring1][=Branch1][Cl][Cl]"}, {"from": "gpt", "value": "The molecule is an organic compound with the formula C6H4Cl2. This colorless solid has a strong odor. In terms of its structure, the molecule consists of two chlorine atoms substituted for hydrogen at opposing sites on a benzene ring. p-DCB is used a pesticide and a deodorant, most familiarly in mothballs in which it is a replacement for the more traditional naphthalene. p-DCB is also used as a precursor in the production of the polymer poly(p-phenylene sulfide). Under California's Proposition 65, p-DCB is listed as known to the State to cause cancer.[8] A probable mechanism for the carcinogenic effects of mothballs and some types of air fresheners containing p-DCB has been identified."}]
