Application

This dipotassium PIPES salt serves as an effective buffering agent for cell culture systems, particularly where phosphate interference must be avoided. It is commonly employed in bacterial growth media, protein crystallization studies, and as a component of electrophoresis running buffers. The compound’s zwitterionic properties make it suitable for maintaining pH stability in redox-sensitive biochemical assays. Researchers also utilize it in chromatography mobile phases to improve peak resolution of biomolecules.
