  • Applications

    Bicyclo(2.2.1)heptane-2-methanol, alpha,3,3-trimethyl-, CAS 66062-78-0. In fragrance chemistry, compounds of this norbornane-based alcohol class are commonly used as fragrance ingredients and fixatives, and as intermediates for subsequent aroma compounds. In cosmetics and personal care, they may be employed as fragrance ingredients or as carriers/solvents for other actives in limited formulations. In household products, cleaners and air fresheners, they can serve as aroma components or formulation aids contributing to odor profile. In coatings and inks, they act as synthetic building blocks or intermediates for specialty monomers or resins. In polymers/plastics, they can serve as building blocks or precursors for specialty polymers. Use is formulation- and regulation-dependent, and handling should follow applicable guidelines.
