  • Applications

    5-(2,3-Dimethyltricyclo[2.2.1.02,6]hept-3-yl)-2-methylpent-2-enyl butyrate (CAS 67633-99-2) is a camphor-like ester that is primarily used as a fragrance ingredient and fixative in practical formulations, while also serving as an organic synthetic intermediate. In perfumery and fragrance applications, it is used as a fragrance component and to extend fragrance notes. In cosmetics and personal care, it can function as a fragrance ingredient. In household products such as cleaners, detergents, and air fresheners, it acts as an odorant/fragrance additive. In coatings, paints, and inks, it may be used as a fragrance additive or odorant. In industrial manufacturing, it may be evaluated as an organic intermediate for chiral camphor-like derivatives. Its use is subject to local regulations and formulation limits.
