Sodium acetate anhydrous is widely used as a buffering agent in biochemical, molecular biology, and chemical applications to maintain stable pH levels. In the textile industry, it acts as a neutralizing agent in dyeing processes to neutralize sulfuric acid waste streams and as an auxiliary chemical in dye production. In the food industry, it serves as a preservative (E262) and flavoring agent, enhancing the taste of products like snacks and chips. It is employed in reusable heating pads and hand warmers, where it releases heat upon crystallization of the hydrated form. In wastewater treatment, it functions as a carbon source for denitrification processes to reduce nitrate levels. Additionally, it is used in leather tanning to adjust pH and condition the hide, as an ingredient in electrolyte solutions for certain batteries, and in medical applications as a component in intravenous solutions for treating dehydration and electrolyte imbalances.
