Applications

Phosphorus(V) oxide is used as a drying and dehydrating agent, a condensation reagent in organic synthesis and a laboratory reagent. It is also used in sugar refining and in fire extinguishing. Phosphorus pentoxide in DMSO forms an Onodera reagent which oxidizes alcohols. It is capable of converting mineral acids to anhydrides.

Notes

It is highly hygroscopic in nature and gets hydrolyzed to phosphoric acid. It is stored in a separate safety cabinet away from incompatibles such as alkali and water.
