General description

Deuterium oxide (D2O) is also known as heavy water. It is the deuterated form of water, as both the protons in H2O have been replaced with a deuterium isotope.

Application

D2O can be used as a solvent in:      
  • High-resolution NMR (Nuclear magnetic resonance)      
  • FTIR (Fourier-transform infrared)      
  • Bio NMR studies      
  • Polarized visible Raman spectroscopic studies      
  • Protein expression

D2O 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, and the structure of biomolecules, and residual agrochemicals in foods using suitable analytical methods.
