DIPSO sodium salt is widely used as a biological buffer in biochemical and molecular biology research. It helps maintain a stable pH in cell culture media and enzyme assays, ensuring optimal conditions for biological processes. Its effectiveness in the pH range of 7.0 to 8.2 makes it suitable for various applications, including protein purification, nucleic acid studies, and cell-based experiments. Additionally, it is often employed in diagnostic kits and pharmaceutical formulations where precise pH control is critical. Its low toxicity and compatibility with biological systems further enhance its utility in life sciences.
