Potassium Phosphate Dibasic, Anhydrous, also known as dipotassium phosphate, is a chemical compound that plays a significant role in life science research, particularly in molecular biology, cell culture, and biochemistry.

Potassium Phosphate Dibasic, Anhydrous, is primarily utilized as a buffering agent to maintain a stable pH in various experimental procedures. It acts as a powerful pH regulator and is particularly effective in the pH range of 7.0 to 8.0, making it suitable for applications requiring neutral to slightly alkaline pH conditions.

It is commonly used in cell culture media, protein purification, and enzyme assays where a specific pH range needs to be maintained. Its buffering capacity and stability within the desired pH range make it valuable in these applications.

Additionally, Potassium Phosphate Dibasic, Anhydrous, is a source of potassium ions, an essential nutrient for many biological processes. It can serve as a supplement in cell culture media and nutrient solutions to provide a balanced and optimal environment for cell growth and metabolism.
