Used as a solvent in organic synthesis, particularly in reactions requiring polar aprotic conditions. Enhances solubility of reagents and intermediates, making it valuable in pharmaceutical manufacturing and polymer chemistry. Also serves as a reaction medium in metal-catalyzed coupling reactions due to its stability and ability to coordinate with metal ions. Its low volatility and high boiling point make it suitable for high-temperature processes. Additionally, employed in extraction processes and as a carrier in specialty formulations where water resistance and thermal stability are needed.
