Used primarily as a polar aprotic solvent in organic synthesis, enabling a wide range of nucleophilic substitution reactions due to its ability to dissolve both polar and nonpolar compounds. It is effective in facilitating reactions such as the Swern oxidation, where it acts as an oxidant precursor. Commonly employed in pharmaceutical manufacturing for the synthesis of active ingredients, especially where high solvating power and thermal stability are required. Also utilized in polymer science to process and modify polymers, and in electronics for cleaning and etching semiconductor materials. Its high boiling point and miscibility with water and organic solvents make it valuable in extraction and purification processes.
