Hexane-d14 is widely used as a solvent in nuclear magnetic resonance (NMR) spectroscopy due to its deuterated nature, which minimizes interference with the NMR signals of the sample being analyzed. It serves as an excellent reference compound for calibrating NMR instruments and studying molecular structures, particularly in organic chemistry and biochemistry research. Additionally, it is employed in the synthesis of deuterated compounds, where the replacement of hydrogen with deuterium is necessary for specific experimental or analytical purposes. Its non-reactive and stable properties make it suitable for use in various isotopic labeling studies, aiding in the tracking and understanding of chemical reactions and mechanisms.
