Used primarily as a comonomer in the production of polyethylene, especially linear low-density polyethylene (LLDPE), 1-pentene improves the strength, flexibility, and impact resistance of the final plastic product. It is also utilized in the synthesis of alcohols, plasticizer alcohols, and other organic compounds through processes like hydroformylation. Additionally, it serves as a chemical intermediate in the manufacture of detergents, surfactants, and lubricants. Its reactivity makes it valuable in petrochemical industries for producing higher olefins and branched hydrocarbons.
