PERSADOX (94-36-0) Combustible solid (autoignition temperature 176°F/80°C). Power, dust, or vapor forms explosive mixture with air. Confined storage of dry chemical may lead to decomposition and explosion. A strong oxidizer extremely reactive with many substances. An explosive that is sensitive to friction, shock, and heat may decompose below the melting point of 217°F/103°C. Fire and/or explosions may result from contamination contact with strong acids, combustible materials, reducing agents, oxidizers, acids, bases, alcohols. 

Combustible liquid flash point (open cup) 55°C (131°E) vapor pressure 0.4 torr at 20°C (68°E) autoignition temperature 369°C (696°E) the vapor forms explosive mixtures with air LEE value 2.7% by volume of air, UEL value not reported fire-extinguishing agent dry chemical, foam, or CO2 use a water spray to keep fire-exposed containers cool, to disperse the vapor, and to blanket the fire. The reactivity of this compound toward most chemicals is low. 

These high energy species are extremely reactive, with themselves and with nucleophiles, and can generate runaway exotherms. With water, rapid evolution of carbon dioxide results. Some instances are reported [1], A compound of this class was resposible for the worst chemical industry accident to date. Di-isocyanates are extensively employed, with polyols, to generate polyurethane polymers. The polymerisation temperature should be held below 180°C or decomposition may occur which, in the case of foams, may induce later autoignition.
