  • Applications

    2H-2,4a-Methanonaphthalen-1(5H)-one, hexahydro-5,5-dimethyl-2-propyl- (CAS 1392277-05-2) is typically used as a specialty intermediate in fragrance chemistry, functioning as an odorant or fragrance modifier with a compact, rigid scaffold. It is commonly evaluated for cosmetics and personal care formulations as a fragrance ingredient contributing woody or amber notes, and may also appear in household products (detergents and cleaners) to influence scent profiles. In industrial manufacturing, it can serve as a synthetic building block or intermediate for further chemical syntheses, including pharmaceutical or agrochemical research, depending on regulatory and purity requirements.
