Application
Ammonium tetrathiomolybdate, a brown to black iridescent crystalline powder, serves multiple purposes across various fields. In synthetic chemistry, it acts as a crucial reagent, while in bioinorganic chemistry, it functions as a valuable building block. Medically, it plays a role in treating copper toxicosis in animals and Wilson's disease by acting as a chelator to lower copper levels in vivo. Its ability to interfere with angiogenesis also makes it significant in reducing tumor growth. Additionally, ammonium tetrathiomolybdate is employed in the synthesis of heterometallic sulfide clusters stabilized by bis(diphenylphosphino)methane (dppm) ligands, and it is involved in the ring opening of aziridines, leading to the formation of sulfides and disulfides.
