General description

Sodium phosphate is a salt of sodium hydroxide and phosphoric acid. It is commonly used in buffers for molecular biology applications. It can also be used as a catalyst in some organic reactions.

Application

Sodium phosphate monobasic can be used:
  • As a catalyst in the synthesis of non-ionic surfactants used for adhesive and detergent applications.
  • As a component of phosphate buffer saline (PBS buffer) used in the study of glucose biosensor.
