Description

5-Undecene is a high-purity, linear α-olefin characterized by its terminal double bond, making it a versatile intermediate for organic synthesis and industrial applications. Its value lies in its reactivity, which enables functionalization for producing specialty chemicals, lubricants, and performance materials. This product is essential for R&D chemists and manufacturers in the fragrance, polymer, and fine chemical industries seeking a reliable building block for synthesis.

Application

• Organic Synthesis Intermediate: A key building block for the production of specialty chemicals, including alcohols, epoxides, and amines via hydroformylation, epoxidation, or hydroamination reactions.
• Fragrance and Flavor Ingredient: Used in the synthesis of specific aroma chemicals and flavor compounds due to its hydrocarbon backbone.
• Polymer and Co-monomer: Serves as a co-monomer in the production of linear low-density polyethylene (LLDPE) and other polyolefins to modify properties.
• Lubricant and Fuel Additive Precursor: A precursor for manufacturing synthetic lubricant base oils and performance-enhancing fuel additives.
• Surface-Active Agent Production: Used in the synthesis of surfactants and detergents through sulfonation or other derivatization processes.
• Laboratory Research: Employed as a standard or reagent in academic and industrial research for studying olefin metathesis and other catalytic transformations.

Quality Control

Our 5-Undecene is produced under stringent quality management protocols to ensure batch-to-batch consistency and high purity. Each lot is analyzed using advanced techniques including Gas Chromatography (GC) to verify identity, assay, and impurity profiles. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, well-ventilated area away from heat and ignition sources. Recommended storage temperature is 2-8°C to minimize oxidation and polymerization. Keep away from strong oxidizing agents.
