Chemical compound
Phosphorus triiodide (PI3) is an inorganic compound with the formula PI3. A red solid, it is[2] too unstable to be stored for long periods of time; it is, nevertheless, commercially available. It is widely used in organic chemistry for converting alcohols to alkyl iodides. It is also a powerful reducing agent.
