Description

General description

Dimethyl sulfoxide (DMSO) is an organosulfur compound which is a dipolar aprotic solvent. It remains liquid across a broad temperature range, acts as a strong electron donor, and possesses high polarity. These characteristics make it an excellent and selective solvent for a variety of organic and even polymeric compounds. DMSO is a widely used solvent in organic synthesis and analytical applications since it is fully miscible with water and various organic solvents, enabling it to dissolve both polar and nonpolar substances. [1] [2] [3]

Application

DMSO is used

• As a solvent in the synthesis of 3,5-Diiodo-8-aryl-BODIPYs by Double Aromatic Finkelstein Reaction. [3]
• As a green solvent in the preparation of novel anticorrosive epoxy coatings. [4]
• As solvent in H¹ nuclear magnetic spectroscopy technique. [5]
