Used as a high-boiling polar solvent in organic synthesis, enabling reactions that require elevated temperatures and good solubility of both organic and inorganic compounds. Commonly employed in the production of pharmaceuticals, agrochemicals, and dyes due to its ability to dissolve a wide range of substances. Plays a key role in the synthesis of acrylic fibers and polyacrylonitrile. Also used in the manufacture of pesticides and in solvent extraction processes. Its polarity and stability make it suitable for use in peptide coupling and polymerization reactions.
