CAS 1314-56-3: Phosphorus pentoxide
Description:Phosphorus pentoxide, with the chemical formula P2O5 and CAS number 1314-56-3, is a white, crystalline solid that is highly hygroscopic, meaning it readily absorbs moisture from the air. It is primarily used as a dehydrating agent and in the production of phosphoric acid. The substance has a high melting point and can exist in various forms, including an amorphous state and a crystalline form known as the anhydride of phosphoric acid. When it comes into contact with water, phosphorus pentoxide reacts vigorously, forming phosphoric acid. It is also known for its ability to act as a strong desiccant, making it useful in various chemical processes and laboratory applications. Due to its reactivity, phosphorus pentoxide should be handled with care, as it can cause irritation to the skin, eyes, and respiratory system. In terms of storage, it should be kept in a tightly sealed container in a cool, dry place to prevent it from absorbing moisture and degrading.
