General description

Deuterium oxide (D2O) is also known as heavy water. It is commonly used as a solvent in high-resolution NMR (Nuclear magnetic resonance) FTIR (Fourier-transform infrared) and polarized visible Raman spectroscopic studies. It is also used to prepare deuterium-labeled compounds in various fields such as pharmaceutical, bioanalytical, biological, and environmental chemistry via H-D exchange reactions to study drug metabolism mechanisms, reaction mechanisms, the structure of biomolecules, and residual agrochemicals in foods using suitable analytical methods.
