Description

3,7-Dimethyl-2-Octen-1-Ol is a monounsaturated, branched-chain fatty alcohol with a characteristic floral, citrus-like odor. This compound is a key intermediate and fragrance ingredient valued for its stability and versatility in fine chemical synthesis. It is primarily utilized by manufacturers in the fragrance and flavor, pharmaceutical, and agrochemical industries for creating complex aroma profiles and bioactive molecules.

Application

• Fragrance & Flavor Industry: A crucial building block for synthesizing terpenoid-based fragrance compounds like citronellol and hydroxycitronellal, imparting fresh, floral, and citrus notes to perfumes, cosmetics, and personal care products.
• Pharmaceutical Intermediates: Serves as a chiral synthon in the production of certain vitamins (e.g., Vitamin E analogs) and other biologically active compounds requiring specific stereochemistry.
• Agrochemical Synthesis: Used in the manufacture of certain pesticides and pheromones, leveraging its structural similarity to natural insect communication chemicals.
• Fine Chemical Production: Acts as a precursor for surfactants, plasticizers, and other specialty chemicals where a defined carbon chain length and olefinic functionality are required.
• Research & Development: Employed in academic and industrial R&D for organic synthesis, catalysis studies, and material science due to its reactive alcohol and alkene groups.

Quality Control

Our 3,7-Dimethyl-2-Octen-1-Ol is produced under a strict quality management system. Each batch is analyzed to ensure it meets stringent specifications for identity, purity, and olfactory profile. Certificates of Analysis (COA) detailing chromatographic purity, isomer content, and physical constants are available upon request. We can supply material compliant with relevant standards for fragrance and industrial use.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area at 15-25°C. Due to its properties of being easily oxidized and highly volatile, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation and to minimize headspace in partially used containers. Keep away from heat, sparks, and open flame.
