Application


  • HFIP-Mediated Multicomponent Reactions: Research demonstrates the use of HFIP (Hexafluoroisopropanol) in synthesizing pyrazole-linked thiazole derivatives, highlighting a new application in organic synthesis. Glyoxal is instrumental in the development of these multifunctional structures, contributing to advanced material design (Banerjee et al., 2024).

  • Peptide Stapling in Protein Engineering: A study describes peptide stapling techniques using alpha-ketoaldehydes, which crosslink amines through glyoxal-modified linkers. This approach is pivotal in creating stable peptide structures for therapeutic applications (Guo et al., 2024).
