Thiosemicarbazones are organic compounds resulting from the condensation of thiosemicarbazide with a carbonyl group, characterized by the presence of a -NH-CS-NH-CO- functional structure and widely used in chelation therapy due to their ability to form stable complexes with various metal ions.
Radionuclide Generators
Separation systems containing a relatively long-lived parent radionuclide which produces a short-lived daughter in its decay scheme. The daughter can be periodically extracted (milked) by means of an appropriate eluting agent.
Copper Radioisotopes
Unstable isotopes of copper that decay or disintegrate emitting radiation. Cu atoms with atomic weights 58-62, 64, and 66-68 are radioactive copper isotopes.
Organometallic Compounds
A class of compounds of the type R-M, where a C atom is joined directly to any other element except H, C, N, O, F, Cl, Br, I, or At. (Grant & Hackh's Chemical Dictionary, 5th ed)
Pyruvaldehyde
An organic compound used often as a reagent in organic synthesis, as a flavoring agent, and in tanning. It has been demonstrated as an intermediate in the metabolism of acetone and its derivatives in isolated cell preparations, in various culture media, and in vivo in certain animals.
