[{"from": "human", "value": "Could you provide a description of this molecule? [C][=Branch1][C][=N-1][=O]"}, {"from": "gpt", "value": "The molecule are a class of liquid compounds which are generally colorless with slight odors. Many of these compounds are extremely flammable, toxic by inhalation, and irritants to skin, eyes and mucous membranes. Most isocyanates will react with water to generate toxic fumes, and when heated to high temperatures they may decompose to emit toxic nitric oxides and cyanide fumes. Obtain the technical name of the material from the shipping papers and contact CHEMTREC, 800-424-9300 for specific response information. They are used to make other chemicals."}]
