Dimethyl Sulfone CAS 67-71-0 MSM

As a highly efficient polar solvent, it is widely used in electronic (cleaning agent) and chemical fields, combining strong solubility and low-temperature anti-freezing properties. It needs to be sealed and kept away from light. Its high permeability may irritate the skin, so protective equipment should be worn when handling.
