  • Applications

    2-Naphthalenol, 1,2,3,4,5,6,7,8-octahydro-2,5,5-trimethyl-, (2S)- (CAS 670-24-6) is primarily used as a synthetic building block and aroma-chemical intermediate in fragrance chemistry. In perfumery, it can serve as a fragrance ingredient or fixative that contributes to odor profiles; in cosmetics and personal care, it may be employed as a fragrance component within formulation limits. It also finds application in household products such as cleaners and air fresheners where it contributes to scent. In industrial manufacturing, it is used as an intermediate for the synthesis of specialty aroma compounds and related chemicals. In polymers and coatings sectors, it may be used as a niche precursor or fragrance-related additive in select formulations, with actual use governed by local regulations and formulation constraints.
