Water-17O (H217O) is a colorless liquid at room temperature. The density of 17O water is 1.044 g/cm3 at 20 ° C and it boils at 100 ° C.


17O water, or 17O labelled water, is prepared by reducing copper (I) oxide with hydrogen:

Cu217O + H2 → Cu + H217O

17-O water (H217O) is used in different fields of chemistry. The most known applications are the following:

  • Oxygen‑17 (O‑17) Water is now being used for diagnostic applications and medical research to create a new generation of NMR Images;
  • ​New developments with O‑17 enhance the quality of information about living tissue to improve the practice of medicine in the fields of cardiology and neurology;
  • Commonly used in organic synthesis as the source of 17O isotope;
