Description

Henicosene is a high-purity, long-chain terminal alkene (C21:1) valued for its role as a versatile chemical intermediate and building block in advanced organic synthesis. Its linear structure and terminal double bond make it a critical raw material for producing surfactants, lubricant additives, and specialty polymers. This product is essential for R&D laboratories and industrial manufacturers in the oleochemical, specialty chemical, and materials science sectors seeking reliable, high-quality feedstocks.

Application

• Organic Synthesis Intermediate: A key building block for the production of longer-chain olefins, alcohols, and other derivatives via hydroformylation, epoxidation, or metathesis reactions.
• Surfactant & Detergent Precursor: Used in the manufacture of olefin sulfonates and other anionic surfactants for industrial and household cleaning formulations.
• Lubricant & Fuel Additive Synthesis: Serves as a precursor for polyalphaolefins (PAOs) and other performance additives that enhance viscosity index and thermal stability.
• Polymer & Co-modifier: Acts as a co-monomer or chain transfer agent in the production of polyethylene, polyolefin elastomers, and waxes to modify physical properties.
• Fine Chemical & Pharmaceutical Intermediate: Employed in the synthesis of complex molecules for agrochemicals, pharmaceuticals, and fragrances.
• Research & Development: A standard compound for chromatography, calibration, and material science research due to its defined molecular weight and structure.

Quality Control

Our Henicosene is produced under a strict quality management system to ensure batch-to-batch consistency and high purity. Each lot is analyzed using advanced techniques including Gas Chromatography (GC) and meets rigorous internal specifications. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from strong oxidizing agents, heat, and ignition sources. For long-term storage, consider under an inert atmosphere such as nitrogen to minimize potential oxidation.
