  • Applications

    In green and specialty chemistry, (1R,4S,6S)-1-methyl-4-(prop-1-en-2-yl)-7-oxabicyclo[4.1.0]heptane (an enantiomer of limonene oxide; CAS 4959-35-7) serves as a bio-based chiral pool building block for stereoselective epoxide ring-opening to diols, amino alcohols, ethers, and esters; as a precursor to cyclic carbonates via CO2 fixation en route to bio-derived polycarbonates and non-isocyanate polyurethanes; as a reactive diluent/modifier in epoxy and UV-curable coatings to boost bio-based content; as an intermediate to terpene-derived aroma ingredients and stereo-defined pharma/agro scaffolds; and as an analytical reference and model substrate in studies of epoxide ring-opening, catalytic CO2 utilization, and sustainable materials chemistry.
