  • Applications

    Gallium Maltolate (CAS 108560-70-9) is the chelated gallium(III) complex formed with maltol and is commonly used in research as a gallium source and as a coordinating ligand. In analytical and coordination chemistry, it serves as a reagent for preparing Ga(III) complexes and for studying metal-ligand interactions. It is also investigated in pharmaceutical and biomedical research as a potential tool to probe gallium biology, with consideration of diagnostic or therapeutic exploration. In materials science, it can function as a precursor or enabling ligand for the synthesis of Ga-containing materials and catalysts. Subject to local regulations and formulation limits.
