What is Phosphorus Oxychloride?

Phosphorus oxychloride (POCl₃, phosphoryl chloride) is an inorganic compound with a tetrahedral molecular geometry in which a phosphorus atom is bonded to three chlorine atoms and one oxygen atom via a P=O double bond. It is a highly reactive, fuming liquid that reacts vigorously with water to produce phosphoric acid and hydrogen chloride. POCl₃ is widely used as a chlorinating agent in organic synthesis, particularly for the preparation of organophosphorus compounds and in the synthesis of pharmaceuticals and pesticides.
