How Does DMSO (Dimethyl Sulfoxide) Work As A Solvent?

Dimethyl sulfoxide (DMSO) is defined as a polar organic solvent that is soluble in both aqueous and organic environments, known for its ability to disrupt hydrogen bonds and transport small molecules through barriers.

Why is DMSO (Dimethyl Sulfoxide) used as a solvent?

DMSO is a laboratory and industrial solvent for many gases, synthetic fibers, paint, hydrocarbons, salts, and natural products. Because it is aprotic, relatively inert, nontoxic, and stable at high temperatures, it is a frequently used solvent for chemical reactions.
