Used primarily as a buffering agent in biochemical and molecular biology applications, it helps maintain stable pH levels in various experimental conditions. It is particularly effective in cell culture media, enzyme assays, and protein purification processes due to its compatibility with biological systems. Additionally, it is employed in electrophoresis and chromatography techniques to ensure optimal separation and analysis of biomolecules. Its low toxicity and minimal interference with biochemical reactions make it a preferred choice in research and industrial settings.
