In this study, the favorable feasibility of deep eutectic solvents (DESs) in solubilization and functionalization of natural heteropolysaccharide was validated by experiments and d. functional theory calculations This revealed that choline chloride-based DES/DMSO (DMSO) binary mixed solvents possessed more and stronger hydrogen bonding sites, facilitating the balance between disruption and reconstruction of hydrogen bonds within branched heteropolysaccharide from Artemisia sphaerocephala (PAS) and achieving efficient solubilization. Further, due to the full exposure and activation of polysaccharide hydroxyls, the efficiency of DES/DMSO-mediated novel Se-functionalization was substantially enhanced compared to the conventional selenylation methods. The derivative exhibited conversion to lower mol. mass with rigid solution conformation based on co-solvent effect and predominant acidic environment influence. This study offered a framework for exploring the potential of individualized polysaccharide functionalization by modulating DES constituents to achieve multiple controls in terms of conversion efficiency and derivative structure. This study involved multiple reactions and reactants, such as Tetramethylammonium chloride (cas: 75-57-0Application In Synthesis of Tetramethylammonium chloride).
Tetramethylammonium chloride (cas: 75-57-0) belongs to organic chlorides. Chlorinated organic compounds are found in nearly every class of biomolecules and natural products including alkaloids, terpenes, amino acids, flavonoids, steroids, and fatty acids. Alkyl chlorides readily react with amines to give substituted amines. Alkyl chlorides are substituted by softer halides such as the iodide in the Finkelstein reaction.Application In Synthesis of Tetramethylammonium chloride
