Description

(E)-2,2,4,6,6-Pentamethyl-4-Heptene is a high-purity, branched-chain olefin characterized by its unique sterically hindered structure. This compound matters as a versatile intermediate and specialty solvent, offering excellent solvency and stability for demanding chemical synthesis and formulation processes. It is needed by manufacturers in the fragrance, agrochemical, and polymer industries, where its specific isomerism and volatility are critical for performance.

Application

• Fragrance and Flavor Intermediate: Serves as a key building block for synthesizing musky, woody, or amber-like aroma chemicals due to its stable, branched hydrocarbon backbone.
• Agrochemical Synthesis: Used as an intermediate in the production of certain pesticides and herbicides, where its structure can contribute to product efficacy and environmental profile.
• Specialty Solvent: Acts as a high-performance, non-polar solvent for resins, polymers, and chemical reactions requiring an inert, low-reactive medium.
• Polymerization Modifier: Functions as a chain transfer agent or comonomer in the synthesis of specialized polyolefins to control molecular weight and introduce branching.
• Organic Synthesis Intermediate: Utilized in research and fine chemical production for reactions like hydroformylation or hydrogenation to create more complex molecules.
• Lubricant and Fuel Additive Component: Employed in the formulation of high-performance lubricants and fuel additives to enhance properties like viscosity index and stability.

Quality Control

Our (E)-2,2,4,6,6-Pentamethyl-4-Heptene is produced under stringent quality management systems. Every batch undergoes rigorous analytical testing, including GC and GC-MS, to ensure high isomeric purity and the absence of critical impurities. Certificates of Analysis (COA) detailing identity, assay, and specific parameters are available upon request 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. Due to its highly volatile and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation. Keep container tightly sealed when not in use to prevent evaporation and potential oxidation.
