DMSO, a highly polar aprotic solvent, is widely used in organic synthesis reactions, catalytic systems, and polymerization reactions. It is the preferred solvent for reactions such as Grignard reactions and nucleophilic substitution.
Used for drug dissolution and permeability enhancement
Serves as a key component in cell cryopreservation solutions
Serves as a raw material for the preparation of various pharmaceutical intermediates
In the electronics industry, DMSO is used for photoresist cleaning, liquid crystal display manufacturing, and as a diluent in battery electrolytes, particularly in applications requiring strict impurity control.
Serves as a pesticide solvent and penetrant, improving the absorption rate of active ingredients. It also serves as a sustained-release agent in control agent formulations.
Used for metal surface treatment, resin release, and natural product extraction, it exhibits excellent solubility and thermal stability.
