Water-18O Chemical Properties,Usage,Production

Description

Only 0.2% of the oxygen-18O isotope exists in atmospheric oxygen. The Water-18O is manufactured by enriching the oxygen-18O over 98 atom% and is used to produce the [18F]FDG *1 PET diagnostic reagent for cancer. Water enriched in the oxygen-18 isotope (Water-18O) is widely used in medicine, agrochemistry and biochemistry. Oxygen-18 was first enriched to 99.5% in 1943 using thermal diffusion. To date, the use of electrolysis, chemical isotope exchange, gas diffusion, and rectification of oxygen, nitric oxide, and water has been described to enrich water with oxygen-18. Among them, the method of rectification of water, first demonstrated in 1944, is successfully used now in industry.

Chemical Properties

Colourless Liquid

Uses

Water-18O, 97 atom % 18O is used in DNA stable isotope probing (SIP) to investigate microbial growth and death in environmental samples.

Uses

Water-18O is an isotopically modified water, which is appropriate for PET applications.
It can also be used:

  • In paleoclimatology, hydrology, and plant ecology to determine soil stable oxygen isotope analysis of plant cellulose using δ18O.
  • To determine the diffusion of moisture into crystals using secondary ion mass spectrometry (SIMS).

Definition

ChEBI: A form of water consisting of two hydrogen atoms covalently bonded to an oxygen-18 atom.
