  • Applications

    (3,5-Dimethylcyclohex-3-en-1-yl)methanol, CAS 67634-16-6, is an alicyclic cyclohexene derivative bearing a hydroxymethyl group and two methyl substituents on the ring. In real-world use, it is commonly employed as an odorant and fragrance ingredient in perfumery and cosmetics; it can serve as a fragrance component in household products and personal care items; it may be used as a synthesis building block or intermediate for other aroma compounds in industrial manufacturing; and it may be evaluated for fragrance or flavor applications in food-related formulations, subject to local regulations and formulation limits.
