Used as a solvent and reaction medium in organic synthesis due to its high boiling point and ability to dissolve a wide range of organic and inorganic compounds. It is particularly useful in metal-catalyzed reactions and anionic polymerizations where stability and solvating power are important. Also employed as a plasticizer and in the formulation of specialty cleaning fluids and coatings. Its low toxicity and good thermal stability make it suitable for applications requiring prolonged exposure or elevated temperatures.
