Chloroform-d is widely used as a solvent in nuclear magnetic resonance (NMR) spectroscopy. Its deuterated form reduces interference from hydrogen signals, providing clearer and more precise spectra for analyzing organic compounds. It is particularly valuable in studying molecular structures and dynamics in chemistry and biochemistry research. Additionally, it serves as a reference standard in NMR due to its consistent and well-defined spectral properties. Its application extends to the synthesis of deuterated compounds, where it acts as a source of deuterium in various chemical reactions.
