Description

9-Eicosene is a high-purity, long-chain terminal alkene (α-olefin) with the CAS registry number 42448-90-8, valued for its role as a versatile chemical intermediate and building block in organic synthesis. Its linear C20 structure with a reactive terminal double bond makes it a critical raw material for producing surfactants, lubricant additives, and specialty polymers. This compound is essential for R&D and manufacturing in the petrochemical, specialty chemical, and advanced materials sectors.

Application

• Surfactant & Detergent Intermediate: Acts as a key feedstock for the production of linear alkylbenzene sulfonates (LAS) and alcohol ethoxylates, which are primary components in industrial and household cleaning formulations.
• Lubricant & Fuel Additive Synthesis: Used to manufacture polyalphaolefins (PAOs) and other olefin oligomers that enhance viscosity index, thermal stability, and performance of synthetic lubricants and functional fluids.
• Polymer & Co-Monomer: Serves as a co-monomer in the production of linear low-density polyethylene (LLDPE) and other polyolefins to modify density and physical properties, and in the synthesis of specialty waxes.
• Organic Synthesis Building Block: Utilized in hydroformylation, metathesis, and polymerization reactions to create fine chemicals, plasticizers, and other long-chain derivatives.
• Personal Care & Cosmetic Ingredients: A precursor for emollients and conditioning agents used in skin care and hair care products due to its hydrophobic character.
• Research & Development: Employed in academic and industrial laboratories for studying reaction mechanisms and developing new catalytic processes involving long-chain olefins.

Quality Control

Our 9-Eicosene is manufactured under stringent process controls to ensure batch-to-batch consistency and high chemical purity. Quality is verified through a comprehensive suite of analytical techniques including Gas Chromatography (GC) and Nuclear Magnetic Resonance (NMR) spectroscopy. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials such as strong oxidizing agents. For long-term storage, it is recommended to keep the material under an inert atmosphere (e.g., nitrogen) to minimize oxidation. Recommended storage temperature is 2-25°C.
