Description

2,4-Dimethyl-2-[1-Methyl-2-(2,6,6-Trimethyl-2-Cyclohexen-1-Yl)Vinyl]-1,3-Dioxolane is a high-value fragrance intermediate and chemical building block, prized for its unique woody, amber-like olfactory characteristics. Its primary commercial value lies in its role as a precursor and fixative in the creation of sophisticated, long-lasting perfumes and fine fragrances. This compound is essential for manufacturers in the flavor and fragrance (F&F) industry, as well as for research and development chemists working on novel aroma chemicals and specialty organic syntheses.

Application

• Fine Fragrance Formulation: A key ingredient in premium perfumes, colognes, and eau de toilettes, imparting woody, ambery, and musky notes.
• Functional Fragrance Products: Used in personal care items (soaps, lotions, shampoos) and household products (detergents, air fresheners) for scent enhancement and longevity.
• Flavor & Fragrance (F&F) Intermediate: Serves as a critical building block for the synthesis of more complex aroma molecules and specialty esters.
• Organic Synthesis: Utilized in research laboratories as a protected aldehyde equivalent or a chiral synthon for pharmaceutical and agrochemical research.
• Aroma Chemical Production: A direct raw material for manufacturers of specialty aroma chemicals targeting woody, amber, and tobacco scent profiles.
