Oxygen is a vital element, and it is also the most abundant element in the earth's crust. Furthermore, oxygen is an essential component of various biological cells and is used as a standard for measuring the atomic weight of other elements. The oxygen element in nature exists in the three stable isotopes form, including oxygen-16 (16O), oxygen-17 (17O), and oxygen-18 (18O). Oxygen-16 is the most common form of oxygen isotope, with a natural abundance of more than 99%, while Oxygen-17 can be used as an ion to bombard the target material. Oxygen-18 is used as a tracer atom and extensively used in modern high-tech fields (life science, medicine, pharmacy, environmental science, geology, etc.).

Oxygen-18 labeled compounds

Oxygen-18 labeled compound refers to a non-radioactive labeled compound in which the stable isotope oxygen-18 replaces the original oxygen in the compound as a label. Various compounds containing the oxygen-18 label are widely used in chemistry, biology, medicine, environmental science, geology and other fields.
