CAS 10026-13-8: Phosphorus pentachloride

Description: Phosphorus pentachloride (PCl5) is a chemical compound characterized by its molecular structure, which consists of one phosphorus atom bonded to five chlorine atoms. It typically appears as a yellow-green solid at room temperature and is known for its strong reactivity. PCl5 is a powerful chlorinating agent and is often used in organic synthesis to introduce chlorine into various compounds. It can exist in two forms: a molecular solid and a dissociated form in the gas phase, where it can break down into phosphorus trichloride (PCl3) and chlorine gas (Cl2). The compound is highly hygroscopic, meaning it readily absorbs moisture from the air, which can lead to hydrolysis and the formation of phosphoric acid and hydrochloric acid. Due to its reactivity, phosphorus pentachloride must be handled with care, as it can cause severe burns and respiratory irritation upon contact. It is typically stored in tightly sealed containers to prevent moisture ingress and is used in various industrial applications, including the production of chlorinated organic compounds and in the synthesis of phosphorus-containing chemicals.
