Potassium hydrogenphosphate trihydrate(CAS: 16788-57-1)

Potassium hydrogenphosphate trihydrate is a chemical compound with the formula K₂HPO₄·3H₂O. It is a white, crystalline solid that is soluble in water and commonly used as a buffering agent. This compound is stable under normal conditions and has a slightly basic pH when dissolved.

Potassium hydrogenphosphate trihydrate is widely used in pharmaceuticals as a buffering agent, in industrial processes for water treatment, in food as a leavening agent, and in laboratory research for buffer solutions. It also serves as a component in some chemical reagents and fertilizers.

Potassium hydrogenphosphate trihydrate is generally considered safe when handled properly. It is non-toxic in normal use, but direct contact with skin or inhalation of dust should be avoided. Safety data sheets recommend using appropriate protective equipment and following standard chemical handling procedures.

Potassium hydrogenphosphate trihydrate should be stored in a cool, dry place away from direct sunlight. It is best kept in a sealed, airtight container to prevent moisture absorption. Storage at temperatures below 25°C and in low humidity environments ensures maximum stability and prolongs shelf life.
