Descripción

Descripción general

Potassium phosphate monobasic (KH₂PO₄), also known as monopotassium phosphate(MKP), is a soluble salt. It serves as a source of phosphorus and potassium.[1] KH₂PO₄ is an essential component of potassium phosphate buffer, which is utilized in aqueous two-phase systems (ATPS) that are often used in the purification of lipases.[2]

Aplicación

Potassium phosphate monobasic buffer has been used as a component of the mobile phase in high-performance liquid chromatography (HPLC).[3]

Acciones bioquímicas o fisiológicas

Potassium phosphate monobasic (MKP) is a commonly used buffering agent in biochemical and biological applications. It is used as a component of the buffer system in electrophoresis for the separation of biomolecules.[4]
