1-Hexene is a colorless, liquid organic compound with the chemical formula C6H12. It is an industrially important linear alpha-olefin primarily used as a comonomer in polyethylene production. High-density polyethylene (HDPE) and linear low-density polyethylene (LLDPE) typically incorporate 2-4% and 8-10% of 1-hexene, respectively. Its liquid state facilitates easy handling, and gel permeation chromatography can analyze its polymers at or near room temperature. Additionally, 1-hexene serves as a precursor in the hydroformylation process, producing linear aldehydes like heptanoic acid.
