Widely used as a buffering agent in biological and biochemical research to maintain stable pH levels in solutions, particularly in electrophoresis and cell culture applications. It is also employed in the formulation of vaccines and pharmaceuticals to stabilize proteins and other sensitive compounds. Additionally, it serves as a key component in the preparation of buffer solutions for molecular biology techniques, such as DNA and RNA extraction. Its ability to chelate metal ions makes it useful in certain industrial processes and analytical chemistry. Furthermore, it is utilized in cosmetics and personal care products as a pH adjuster and stabilizer.
