  • Applications

    3-Cyclohexene-1-methanol, 2,4-dimethyl- (CAS 67634-17-7) is a chemical intermediate and building block used in fragrance chemistry and specialty chemicals. In the fragrance sector, it is viewed as a precursor for synthesizing aroma compounds and may function as a fragrance fixative. In cosmetics and personal care, it may be employed as a fragrance ingredient or as a precursor for other aroma-related components. In household products, it may serve as a fragrance additive for cleaners and air fresheners to impart or stabilize scent. In industrial manufacturing and coatings, adhesives and plastics, it is used as a precursor to synthesize specialty chemicals and functionalized cyclohexene derivatives for coatings, adhesives, and plastics. Usage is subject to local regulations and formulation limits.
