Sodium acetate buffer is used in molecular biology and biochemistry to maintain stable pH during experiments, particularly in the range of 3.6 to 5.6, especially for DNA and RNA extraction, electrophoresis, and enzyme reactions. It is commonly employed in chromatography and as a buffering agent in pharmaceutical formulations. Additionally, it is applied in the textile industry for dyeing processes and in food as a preservative and flavoring agent. Its ability to resist pH changes makes it valuable in laboratory and industrial processes requiring precise pH control.
