Pertechnetate

The pertechnetate (technetate(VII)) 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. Pertechnetates are salts of technetic(VII) acid. Pertechnetate is analogous to permanganate but it has little oxidizing power.
