PIPES disodium salt (CAS 76836-02-7)

PIPES disodium salt, scientifically known as Piperazine-N,N′-bis(2-ethanesulfonic acid) disodium salt, is a widely used zwitterionic buffer in biological and biochemical research, particularly valued for its excellent buffering capacity within the pH range of 6.1 to 7.5. This buffer is essential in maintaining stable pH conditions, crucial for preventing the denaturation of proteins and other sensitive biomolecules during experiments. Due to its robust pH stabilization properties and minimal interference with biological processes, PIPES disodium salt is especially beneficial in cell culture systems and enzymatic reactions where precise pH conditions are mandatory for optimal activity. Its low affinity for binding metal ions reduces the risk of heavy metal contamination in sensitive reactions, making it ideal for use in molecular biology protocols, including nucleic acid extractions and protein purification processes. Furthermore, its negligible absorption in the UV spectral range ensures that it does not disrupt spectrophotometric measurements, thus supporting accurate and reliable data collection in various research applications. The buffer′s widespread application across diverse scientific fields underscores its effectiveness in enhancing the integrity and reliability of experimental outcomes in research settings.
