Used as a catalyst in organic synthesis processes, particularly in redox reactions such as the oxidation of alcohols to aldehydes or ketones. It offers high efficiency and good selectivity, making it suitable for use in research laboratories and certain types of chemical industries. Additionally, it serves as a precursor for other rhenium compounds used in specialized electronic and optical materials. Its strong oxidizing properties make it valuable in selective oxidation reactions in organic synthesis. It is also employed in studying the properties of rhenium compounds in inorganic and coordination chemistry.
