Description

(+)-Isomenthone CAS NO 1196-31-2 is a high-purity, optically active monoterpene ketone, a key isomer of menthone. This compound is valued for its distinct, fresh, and minty-woody organoleptic profile, making it a critical building block and fragrance ingredient. It is primarily sought after by manufacturers in the flavor and fragrance, pharmaceutical, and agrochemical industries for its role in creating sophisticated aromatic compositions and as a chiral intermediate in synthesis.

Application

• Fragrance & Flavor Industry: A key ingredient in perfumery for creating fresh, minty, and herbal top notes in fine fragrances, personal care products, and air fresheners.
• Flavor Formulations: Used to impart cooling, mint-like characteristics in oral care products (toothpaste, mouthwash), confectionery, and chewing gum.
• Pharmaceutical Intermediates: Serves as a valuable chiral starting material or intermediate in the synthesis of active pharmaceutical ingredients (APIs) and other fine chemicals.
• Agrochemical Synthesis: Utilized in the production of certain pesticides and herbicides where its specific stereochemistry is required for biological activity.
• Aromatherapy & Wellness: Incorporated into essential oil blends and diffuser products for its refreshing and potentially soothing aromatic properties.
• Chemical Research & Development: Employed as a standard or reagent in organic synthesis and analytical chemistry studies due to its defined stereochemistry.
