Used as a catalyst precursor in olefin polymerization, particularly for the production of polyethylene and polypropylene. It is effective in stereospecific polymerizations when activated with co-catalysts like methylaluminoxane (MAO). The indenyl ligands allow for tunable polymerization control, influencing molecular weight and polymer microstructure. Also employed in research for developing new metallocene-based catalyst systems for advanced polyolefin materials.
