  • Applications

    3,7,7-Trimethylbicyclo[4.1.0]heptan-1-ol is a rigid, hydrophobic bicyclic alcohol whose bulky OH-bearing framework is leveraged as a synthetic intermediate to make acrylate/methacrylate, carbonate, and urethane derivatives for UV-curable inks, coatings, and adhesives to enhance hardness, scratch resistance, and glass-transition temperature (Tg); as a fragrance and cosmetic building block (camphoraceous/woody esters for odor modulation and fixation); and as a precursor in pharmaceutical and agrochemical discovery where a lipophilic bicyclic motif can improve stability and permeability; it is also investigated as a rigid scaffold for asymmetric chemistry, a model for structure-odor relationship studies, an analytical reference material, and a polymer modifier or low-volatility co-solvent to reduce VOC while maintaining film robustness.
