Phosphorus pentoxide p2o5
Manufactured by Merck Group
Sourced in Mexico, United Kingdom
Phosphorus pentoxide (P2O5) is a chemical compound that serves as a desiccant and drying agent. It is a white, crystalline solid that is highly hygroscopic, meaning it readily absorbs moisture from the surrounding environment. The primary function of phosphorus pentoxide is to remove water content from various substances, making it a valuable tool in laboratory and industrial settings.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
