Description

(E)-6,10-Dimethyl-9-Methylene-5-Undecen-2-One is a high-purity, unsaturated ketone of significant commercial interest, primarily recognized for its role as a key fragrance intermediate. Its value lies in its ability to impart unique woody, ambery, and floral olfactory notes, making it essential for creating sophisticated scent profiles. This compound is a critical raw material for perfumers and flavorists in the fragrance, cosmetics, and fine chemical industries seeking to develop premium consumer products.

Application

• Fragrance & Perfumery: A versatile building block for synthesizing complex aroma chemicals, contributing to woody, amber, and floral accords in fine fragrances, personal care products, and home care items.
• Flavor & Food Industry: Used as an intermediate in the creation of flavoring substances that require subtle fruity or floral undertones, subject to appropriate regulatory approvals (e.g., FEMA, EU Flavor Directive).
• Cosmetics & Toiletries: Incorporated into the formulation of scented lotions, creams, shampoos, and soaps to provide a stable and long-lasting fragrance character.
• Aroma Chemical Synthesis: Serves as a crucial precursor in organic synthesis for the production of more complex terpenoid and sesquiterpene derivatives used in various specialty chemical applications.
• Industrial & Functional Fragrances: Applied in air fresheners, detergents, and industrial deodorizers where specific, high-impact scent profiles are required.
• Research & Development: Utilized in academic and industrial R&D laboratories for studying structure-odor relationships and developing novel fragrance molecules.

Quality Control

Our (E)-6,10-Dimethyl-9-Methylene-5-Undecen-2-One is produced under strict quality management systems. Every batch undergoes rigorous analytical testing, including GC, HPLC, and NMR, to ensure high purity, consistent isomeric composition, and the absence of unwanted impurities. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and specific test results is provided with each shipment to guarantee it meets the stringent requirements of the fragrance and flavor industries.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). Due to its sensitivity to oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation. Keep away from heat, sparks, and open flames.
