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.[8] 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.[9] 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.[10] Additionally, lutetium(III) chloride is used in scintillators, materials that emit light when exposed to radiation.[11] These scintillators are crucial in detectors for gamma rays and other high-energy particles, used in both medical diagnostics and in scientific research.[12]
