Description

4,5-Dimethyl-1-Hexene CAS NO 16106-59-5 is a branched-chain α-olefin characterized by its terminal double bond and specific alkyl substitution pattern. This structure makes it a valuable intermediate in organic synthesis, particularly for introducing sterically hindered alkyl groups. It is primarily sought after by research and development laboratories and specialty chemical manufacturers for applications requiring a specific hydrocarbon framework. Its utility spans from polymer modification to serving as a building block for more complex molecules in fine chemical and pharmaceutical synthesis.

Application

• Organic Synthesis Intermediate: A key building block for synthesizing complex molecules, including pharmaceuticals, agrochemicals, and fragrances.
• Polymer & Copolymer Production: Used as a comonomer to modify the properties of polyolefins, influencing characteristics like flexibility, crystallinity, and melting point.
• Lubricant & Fuel Additive Precursor: Serves as a starting material for manufacturing performance-enhancing additives that improve viscosity index, oxidation stability, and detergency.
• Surfactant & Detergent Alkylate: Acts as a hydrophobic feedstock in the production of specialty surfactants for industrial and household cleaning formulations.
• Chemical Research & Development: Employed in academic and industrial R&D for studying reaction mechanisms, catalysis, and developing new synthetic methodologies.
• Specialty Solvent & Extraction Agent: Its specific hydrocarbon structure can be utilized in selective extraction processes or as a solvent for specialized applications.

Quality Control

Our 4,5-Dimethyl-1-Hexene is produced and handled under strict quality management protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including Gas Chromatography (GC) for purity and identity confirmation. A detailed Certificate of Analysis (COA) documenting the specific results for each parameter is provided with every shipment, ensuring full traceability and compliance with your material specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and ignition points. Due to its highly volatile nature, ensure containers are kept tightly sealed when not in use to prevent evaporation and concentration changes. Recommended storage temperature is 2-8°C (refrigerated) for extended stability, though short-term storage at controlled room temperature (15-25°C) is acceptable.
