pertechnetate
The pertechnetate ion is an oxoanion with the chemical formula TcO4−. It is often used as a convenient water-soluble source of isotopes of the radioactive element technetium (Tc). In particular it is used to carry the Tc-99m isotope (half-life 6 hours) which is commonly used in nuclear medicine in several nuclear scanning procedures.
A technetate(VII) is a compound containing this ion. Pertechnetate compounds are salts of technetic(VII) acid. Pertechnetate is analogous to permanganate but it has little oxidizing power.
==Use of pertechnetate to carry technetium-99m==
A technetium-99m generator provides the pertechnetate containing the short-lived isotope Tc-99m for medical uses. This compound is generated directly from molybdate held on alumina within the generator (see this topic for detail).
