Widely used as a buffering agent in pharmaceuticals to maintain stable pH levels in medications, intravenous solutions, and dialysis fluids. It is also employed as an anticoagulant in blood collection tubes, preventing clotting by binding calcium ions. In molecular biology, it serves as a key component in buffers for DNA/RNA precipitation, hybridization protocols, and enzymatic reactions, while acting as a chelating agent to remove inhibitory metal ions and prevent nuclease activity. In the food industry, it acts as a preservative and flavor enhancer, particularly in beverages, dairy products, and processed cheeses. Additionally, it serves as an emulsifier in the production of certain foods, ensuring consistent texture and stability. In cleaning products, it is utilized as a water softener and chelating agent to improve the effectiveness of detergents. Its non-toxic nature makes it suitable for various industrial and consumer applications.
