Description

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.
