  • Applications

    7-Methyl-1-octene (CAS 13151-06-9) is a branched alpha-olefin used primarily as a polymerization feedstock. It serves as a co-monomer in polyolefin production to tailor density, toughness and processability. It also functions as a chemical intermediate for the synthesis of specialty lubricants and surface-active agents. Via hydroformylation and subsequent transformations, it can yield branched aldehydes or alcohols that are employed as fragrance intermediates in perfumery and flavor chemistry. In coatings and inks, it can act as a reactive diluent or co-monomer to adjust resin performance. The use of this chemical is subject to local regulations and formulation limits.
