AMPSO is commonly used as a buffering agent in biochemical and biological research. It is particularly effective in maintaining stable pH levels in various experimental conditions, especially in the pH range of 8.3 to 9.7. This makes it suitable for applications such as cell culture media, protein studies, and enzyme assays where a consistent pH is crucial for optimal activity. Additionally, AMPSO is utilized in electrophoresis and chromatography techniques to ensure accurate separation and analysis of biomolecules. Its low metal ion contamination also makes it a preferred choice in sensitive experiments where trace metals could interfere with results.
