Heavy water (D2O) is a molecule in which the isotope deuterium (D) atom is bonded to an oxygen (O) atom instead of a hydrogen (H) atom. Deuterium contains a neutron that hydrogen does not have, resulting in an increased mass and different physical properties. Heavy water is used as a raw material in pharmaceuticals and as a tracer. Deuterium can be incorporated into drug molecules as a substitute for hydrogen, improving the stability and duration of the drug's effects. Additionally, it is used as a moderator in nuclear power generation. When neutrons collide with deuterium, they lose energy more than when they collide with hydrogen, making nuclear fission reactions more likely. Therefore, heavy water is an essential substance for enhancing the efficiency of nuclear reactors. It is also used as a heavy solvent for NMR. [Features] - Deuterium (D) atoms, an isotope, bond with oxygen atoms instead of hydrogen (H) atoms. - Deuterium contains a neutron that hydrogen does not have. - Increased mass results in different physical properties. *For more details, please refer to the PDF document or feel free to contact us.
