Description

3-Hexen-2-One is a clear, highly volatile liquid with a characteristic green, fruity odor. This unsaturated ketone is a valuable flavor and fragrance intermediate prized for its ability to impart fresh, natural notes to a wide range of formulations. It serves as a key building block for aroma chemicals and is essential for manufacturers in the flavor, fragrance, and specialty chemical industries seeking to create sophisticated organoleptic profiles.

Application

• Flavor & Fragrance Industry: A primary building block for synthesizing aroma chemicals that impart fresh, green, fruity, and unripe notes, such as those found in apple, pear, and tropical fruit flavors.
• Perfumery: Used as a fragrance ingredient and intermediate in fine fragrances, cosmetics, and personal care products to add natural, leafy-green top notes and enhance freshness.
• Food & Beverage Flavors: Employed in the creation of natural-identical and artificial flavorings for candies, beverages, dairy products, and confectionery.
• Agrochemical Intermediates: Serves as a chemical precursor in the synthesis of certain pesticides and pheromones.
• Organic Synthesis: A versatile reagent in organic chemistry for Michael additions, aldol condensations, and other reactions to create more complex molecules.
• Specialty Chemicals: Used in the production of plasticizers, resins, and other specialty materials where its specific ketone functionality is required.

Quality Control

Our 3-Hexen-2-One is produced under strict quality management protocols. Each batch is analyzed to ensure it meets stringent specifications for purity, identity, and organoleptic properties relevant to flavor and fragrance applications. A comprehensive Certificate of Analysis (COA) detailing assay, isomer content, and impurity profiles is provided with every shipment to guarantee consistent quality and traceability.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials. Due to its highly volatile and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation of quality. Keep container tightly sealed when not in use to prevent evaporation and oxidation.
