Used as a catalyst precursor in olefin polymerization reactions, enabling the production of polyethylene and polypropylene with controlled molecular weight and tacticity. It is particularly effective in syndiospecific polymerization of styrene, yielding syndiotactic polystyrene—a high-performance thermoplastic with excellent thermal and chemical resistance. Its organozirconium structure allows for tunable catalytic activity when activated with co-catalysts like methylaluminoxane (MAO). Also employed in research for C–H activation and carbon–carbon bond formation in organic synthesis due to its unique metallocene framework.
