  • Applications

    1,1'-((3,7-Dimethyl-6-octen-1-ylidene)bis(oxy-2,1-ethanediyl))bis(benzene) (CAS 68140-52-3) is a bifunctional aryl-ether compound bearing a terpenoid-like side chain. In practical terms, it is typically evaluated as a specialty intermediate and monomer for polymer and resin formulations; because it can participate in polymerization reactions, it may serve as a crosslinking agent or functional monomer in coatings, resins, and adhesives. It can also function as a plasticizer or co-solvent in industrial formulations. Its terpenoid/aryl-ether structure makes it a candidate fragrance ingredient or fixative in perfumery and household products. Additionally, it may be used as an intermediate in targeted organic synthesis and could be considered for UV-curable coating systems or as a reactive diluent, subject to local regulations and formulation limits.
