Applications:
1. Application as an excellent solvent
DMSO has excellent solubility for organic compounds, inorganic compounds, and polymers, making it one of the most commonly used solvents in organic synthesis.
2. Promoting specific reactions
In addition to its solvent properties, DMSO can promote the efficient progression of various organic reactions by participating in the reaction mechanism or altering the reaction environment.
3. Other special applications
Auxiliary Solvent for Phase Transfer Catalysts: In phase transfer catalytic reactions, DMSO enhances the miscibility between the organic phase and aqueous phase, improving the efficiency of phase transfer catalysts and accelerating reaction progress.
Medium for Radical Reactions: DMSO has a certain stabilizing effect on radicals, serving as a solvent for radical reactions (such as polymerization reactions and halogenation reactions), thereby reducing the coupling inactivation of radicals.
