Deuterium (2H, D)

Deuterium (Hydrogen-2, or D) is one of the stable isotope atom of hydrogen，it contains one proton and one neutron, also known as heavy hydrogen. At present, the research on the introduction of deuterium into new drugs and the intermediate molecules is increasing. These deuterium-containing compounds can also be used as tracers and internal standards, etc.
