Description

5-Undecene, trans- is a high-purity, linear α-olefin characterized by its specific trans-configuration around the double bond. This compound serves as a valuable chemical intermediate and building block in organic synthesis and materials science. It is particularly relevant for industries involved in the production of specialty polymers, fine chemicals, and advanced lubricant additives.

Application

• Organic Synthesis Intermediate: Used in metathesis reactions, hydroformylation, and as a precursor for synthesizing longer-chain olefins, alcohols, and other functionalized derivatives.
• Polymer & Copolymer Production: Acts as a comonomer in the production of linear low-density polyethylene (LLDPE) and other polyolefins to modify properties like density and flexibility.
• Lubricant & Fuel Additive Synthesis: A key raw material for manufacturing synthetic esters and other compounds that enhance the performance of lubricants and fuels.
• Surfactant & Detergent Industry: Employed in the synthesis of olefin sulfonates and other surfactant molecules.
• Fragrance & Flavor Chemistry: Serves as a starting material for the synthesis of specific aroma chemicals and flavor ingredients.
• Research & Development: Utilized in academic and industrial R&D for studying reaction mechanisms and developing new catalytic processes.

Quality Control

Our 5-Undecene, trans- is produced under stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including Gas Chromatography (GC) and spectroscopic methods, to ensure high chemical purity and consistent isomeric composition. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided with each shipment to guarantee traceability and compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, and well-ventilated area, away from heat and ignition sources. Recommended storage temperature is 2-8°C for long-term stability. This material is easily oxidized; ensure containers are properly sealed after each use to minimize exposure to air.
