Used as a precursor in the synthesis of lanthanum-containing materials for catalysis, particularly in organic transformations such as aldol condensations and oxidation reactions. Serves as a dopant or starting material in the preparation of luminescent compounds and phosphors for lighting and display technologies. Employed in sol-gel processes to fabricate lanthanum oxide films and nanostructured materials with applications in electronics and sensors. Also utilized in research for developing new coordination compounds and metal-organic frameworks (MOFs) due to its ability to form stable complexes.
