Phosphorus Pentasulfide CAS#1314-80-3
Phosphorus pentasulfide is a nonmetallic inorganic compound appearing as a yellow to greenish-yellow crystalline solid with an odor resembling hydrogen sulfide. It presents a significant fire hazard and may ignite through friction or upon contact with water. Its boiling point is approximately 995°F (535°C), with an ignition temperature of about 287°F (141°C). When exposed to water or moist air, it decomposes and releases toxic and flammable hydrogen sulfide gas. The compound has a specific gravity of 2.09, making it heavier than water, and is toxic if inhaled, with a TLV of 1 mg/m³ of air. It is assigned UN identification number 1340 and carries an NFPA 704 rating of health 2, flammability 1, and reactivity 2. Phosphorus pentasulfide is primarily used in the production of insecticides, safety matches, ignition compositions, and in sulfonation processes.
