Application


  • Thermophysical Studies: Sodium acetate buffers are used in thermophysical studies to investigate the behavior of protonated and deprotonated glycine in aqueous solutions at various temperatures. This research provides insights into the interactions and stability of biochemical compounds, which are critical for understanding biological processes and developing new analytical methods in biochemistry (Indian Journal of Chemistry - Section A, 2021).
