Used as a precursor in the synthesis of lanthanum-containing materials for catalysis, particularly in organic transformations such as aldol condensations and oxidation reactions. Employed in the preparation of thin films and nanomaterials via sol-gel and chemical vapor deposition methods due to its thermal stability and volatility. Acts as a dopant or starting material in the fabrication of phosphors and luminescent compounds for display and lighting technologies. Also utilized in research for developing lanthanum-based metal-organic frameworks (MOFs) with potential applications in gas storage and separation.
