Used as a solvent in organic synthesis due to its ability to dissolve a wide range of polar and non-polar substances. It is particularly effective in reactions involving organometallic compounds, where its stability and low reactivity are advantageous. Commonly employed in the production of pharmaceuticals, dyes, and resins. Also used as a coupling agent in liquid-liquid extractions and as a component in chromatography mobile phases. Its low volatility and high boiling point make it suitable for use in distillation and reflux processes.
