Used as a precursor in the synthesis of niobium-based catalysts for organic transformations, particularly in oxidation and hydrolysis reactions. Employed in sol-gel processes to fabricate niobium oxide thin films for electronic and optical applications. Serves as a doping agent in the production of specialty glasses and ceramics to enhance refractive index and thermal stability. Also utilized in research for developing new niobium-containing coordination compounds with potential use in material science and catalysis.
