Used as a catalyst in organic synthesis, particularly in selective oxidation and polymerization reactions. Employed in the preparation of scandium-containing ceramics and advanced materials for high-temperature applications. Serves as a precursor in the production of scandium-doped metal oxides used in solid oxide fuel cells and sensors. Also utilized in research for luminescent materials and in the electronics industry for specialty coatings. Its solubility in water and polar solvents makes it suitable for solution-based processing techniques.
