Used primarily in laboratories as a solvent for chemical reactions and extractions, particularly for non-polar compounds. It is also employed in analytical chemistry for sample preparation and in the synthesis of various organic compounds. In industrial settings, it serves as a cleaning agent for removing oils and greases from machinery. Additionally, it is utilized in specialized applications like NMR spectroscopy as a deuterated solvent for studying molecular structures. However, its use is limited due to environmental and health concerns, requiring strict handling protocols.
