Application
- Solid-State NMR Spectroscopy to Probe State and Phase Transitions in Frozen Solutions: This study utilized Sodium phosphate dibasic in the development of formulations for solid-state NMR spectroscopy, focusing on its utility in stabilizing and buffering various chemical environments within in vitro diagnostics manufacturing. This application ensures precise diagnostics by maintaining the integrity of the solution during freezing and thawing cycles (Du et al., 2023).
- Arabinoxylan in Water through SANS: Single-Chain Conformation, Chain Overlap, and Clustering: This paper discusses the application of Sodium phosphate dibasic in the creation of specific buffer solutions for the structural analysis of polysaccharides using small-angle neutron scattering (SANS), a technique often employed in the pharmaceutical and biotechnological industries to ensure high-quality standards in diagnostics production (Petermann et al., 2023).
