[{"from": "human", "value": "Provide a description of this molecule. [C][#Branch1][C][#N][C][#N]"}, {"from": "gpt", "value": "The molecule appears as a colorless gas with an odor of almonds. Freezes at -28 \u00b0C and boils at -20.7 \u00b0C. Shipped as a liquid confined under its vapor pressure. The gas is heavier than air and a flame can travel back to the source of leak very easily. Prolonged exposure to fire or intense heat may cause the containers to violently rupture and rocket. Used to make other chemicals, as a fumigant, and as a rocket propellant."}]
