Used primarily as a precursor in the synthesis of iridium-based catalysts for industrial and laboratory applications. Plays a role in the preparation of iridium nanoparticles and thin films for use in electrochemical devices, such as sensors and fuel cells. Employed in research settings for developing luminescent iridium complexes used in organic light-emitting diodes (OLEDs). Also utilized in specialized chemical vapor deposition (CVD) processes where iridium metal coatings are required for high-temperature and corrosion-resistant applications.
