  • Applications

    Chemical name Cyclohexene, 6-(2-buten-1-ylidene)-1,5,5-trimethyl- (CAS 55497-53-5) is primarily viewed as an intermediate in organic synthesis and as a reactive monomer or co-monomer for specialty polymers and resins; in coatings and inks it may serve as a reactive diluent or crosslinkable component; in adhesives formulations it can act as a building block to enhance crosslink density; in industrial manufacturing it can be a precursor to other cyclohexene-based compounds and specialty materials, and it may have applicability in electronics-related resin systems, with use governed by local regulations and formulation limits.
