Used as a metallocene catalyst in olefin polymerization, particularly for producing high-performance polyolefins with tailored molecular structures. It enables precise control over polymer stereochemistry, molecular weight, and comonomer incorporation, making it valuable in manufacturing specialty plastics such as linear low-density polyethylene (LLDPE) and isotactic polypropylene. The catalyst is often activated with methylaluminoxane (MAO) or other cocatalysts in industrial and laboratory settings. Its bridged indenyl ligand structure enhances thermal stability and stereoselectivity during polymerization reactions.
