[C][=C][C][=C][C][=C][C][=C][C][Ring1][=Branch1][=C][Ring1][#Branch2]"}, {"from": "gpt", "value": "The molecule appears as a white crystalline volatile solid with a strong coal-tar odor. The solid is denser than water and insoluble in water. Burns, but may be difficult to ignite.  In the molten form it is very hot. Exposure to skin must be avoided. Also the vapors given off by the material may be toxic.  Used as a moth repellent, fumigant, lubricants, and to make other chemicals, and for many other uses"}]
