Used as a precursor in the synthesis of scandium-containing materials for catalysis, particularly in organic transformations such as Friedel-Crafts reactions and polymerization processes. Employed in the preparation of scandium oxide films and ceramics via sol-gel methods, useful in solid oxide fuel cells and high-temperature materials. Also applied in research for luminescent compounds and as a dopant in phosphors for lighting and display technologies. Its hydrate form supports solubility and stability in aqueous-based processing, making it suitable for laboratory-scale development of scandium complexes and functional materials.
