Description

3-Octadecene is a high-purity, long-chain terminal alkene with the CAS number 7206-19-1, serving as a versatile intermediate in organic synthesis. Its linear C18 structure with a reactive double bond makes it a valuable building block for creating surfactants, lubricant additives, and specialty polymers. This product is essential for R&D laboratories and industrial manufacturers in the chemical, material science, and pharmaceutical sectors seeking reliable, high-quality olefinic raw materials.

Application

• Organic Synthesis Intermediate: A key starting material for hydroformylation, epoxidation, and metathesis reactions to produce aldehydes, epoxides, and higher olefins.
• Surfactant & Detergent Precursor: Used in the manufacture of olefin sulfonates and other anionic surfactants for industrial and household cleaning formulations.
• Lubricant & Fuel Additive Component: Acts as a co-monomer or modifier in the synthesis of polyalphaolefins (PAOs) and other synthetic lubricants and fuel additives.
• Polymer Science: Employed as a comonomer in copolymerization reactions and as a chain transfer agent to control polymer molecular weight.
• Research & Development: A standard reagent in catalytic studies, material science research, and the development of new organic methodologies.
• Fine Chemical Production: Serves as a hydrophobic alkyl chain introducer in the synthesis of agrochemicals, pharmaceuticals, and fragrances.
