Lutetium(III) chloride or lutetium trichloride is the chemical compound composed of lutetium and chlorine with the formula LuCl3. It forms hygroscopic white monoclinic crystals[3] and also a hygroscopic hexahydrate LuCl3·6H2O.[6] Anhydrous lutetium(III) chloride has the YCl3 (AlCl3) layer structure with octahedral lutetium ions.[7]
Lutetium-177, a radioisotope that can be derived from Lutetium(III) chloride, is used in targeted cancer therapies. When Lutetium-177 is attached to molecules that specifically target cancer cells, it can deliver localized radiation to destroy those cells while sparing surrounding healthy tissue. This makes Lutetium-177-based treatments especially valuable for cancers that are difficult to treat with traditional methods, such as neuroendocrine tumors and prostate cancer. Additionally, Lutetium(III) chloride is used in scintillators, materials that emit light when exposed to radiation. These scintillators are crucial in detectors for gamma rays and other high-energy particles, used in both medical diagnostics and in scientific research.
Reactions
Pure lutetium metal can be produced from lutetium(III) chloride by heating it together with elemental calcium:[8]
