Widely used as a catalyst in polymerization reactions, particularly in the synthesis of polyolefins such as polyethylene and polypropylene. It serves as a key component in Ziegler-Natta catalyst systems, enabling control over polymer molecular weight and microstructure. Its organometallic structure allows for high catalytic activity under mild conditions, making it valuable in industrial plastic production. Also employed in academic research for studying metallocene-based catalysis and reaction mechanisms in organozirconium chemistry.
