Used extensively in biological and biochemical research to maintain stable pH levels in various experimental conditions. It is particularly valuable in cell culture media, enzyme assays, and protein purification processes. The buffer is also employed in diagnostic kits and medical tests to ensure accurate results by preventing pH fluctuations. Additionally, it finds application in the food industry as a pH regulator and preservative, enhancing the shelf life and stability of products. Its compatibility with biological systems makes it a preferred choice in pharmaceutical formulations, where it helps maintain the efficacy and stability of active ingredients.
