Description

(R)-(-)-10-Methyl-1(9)-Octal-2-One CAS NO 63975-59-7 is a high-purity, chiral fragrance and flavor intermediate characterized by its specific stereochemistry and unique organoleptic properties. This compound is valued for its ability to impart sophisticated, woody, and amber-like nuances, making it a critical building block in the creation of premium fragrance compositions. It is primarily sought after by research and development chemists and manufacturers in the flavor and fragrance (F&F) industry, as well as by fine chemical suppliers serving the cosmetics and personal care sectors.

Application

• Fragrance Formulation: As a key chiral ingredient for creating complex, long-lasting woody, amber, and musk accords in perfumes, colognes, and fine fragrances.
• Flavor Enhancement: Used in trace amounts to add depth and sophisticated woody or earthy notes to specialty food and beverage flavorings.
• Cosmetic Ingredients: Incorporated into high-end personal care products such as lotions, soaps, and shampoos for its aromatic properties.
• Chemical Synthesis: Serves as a valuable chiral synthon or intermediate in the asymmetric synthesis of more complex fragrance molecules and pharmaceuticals.
• Aromatherapy & Home Care: Used in the formulation of premium diffuser oils, scented candles, and household air care products.
• Research & Development: Employed in academic and industrial R&D for studying structure-odor relationships and developing new chiral compounds.
