Citric Acid Anhydrous, 1 kg, is a high-purity reagent used primarily in research and industrial applications as a buffering agent. Citric acid is widely used in chemical reactions that require pH regulation, such as in biochemical assays, pharmaceutical formulations, and food processing. It is also employed in the production of citrate salts, used in a variety of applications including the preservation of biological samples and the regulation of calcium levels in living organisms. This anhydrous form of citric acid is favored for its higher stability and purity, making it ideal for precise formulations in scientific research and product development.
