Used in research and development of niobium-containing materials, particularly in vapor deposition processes to create thin films for electronic and optical applications. Serves as a precursor in the synthesis of niobium-based catalysts and specialized inorganic compounds. Its high reactivity makes it suitable for use in controlled environments for producing niobium iodides with lower oxidation states. Limited industrial use due to sensitivity to moisture and air, but valuable in specialized laboratory settings for exploring niobium chemistry.
