Description

9-Methyl-1-Decene is a branched-chain α-olefin of significant industrial interest, primarily valued for its role as a versatile chemical intermediate and monomer. Its unique structure, featuring a terminal double bond and a methyl branch, makes it a valuable building block for synthesizing specialized polymers, lubricants, and fine chemicals. This product is essential for R&D laboratories and industrial manufacturers in the polymer, specialty chemical, and lubricant additive sectors seeking to develop materials with tailored properties.

Application

• Polymer & Copolymer Production: Acts as a comonomer for producing linear low-density polyethylene (LLDPE) and other polyolefins to modify density, crystallinity, and mechanical properties.
• Synthetic Lubricant & Oil Additive Synthesis: Used in the manufacture of polyalphaolefins (PAOs) and other synthetic base stocks, as well as performance additives like viscosity index improvers.
• Organic Synthesis Intermediate: Serves as a key starting material or intermediate in organic synthesis for pharmaceuticals, agrochemicals, and specialty surfactants due to its reactive terminal alkene.
• Plasticizer & Surfactant Alcohols: A precursor for producing plasticizer alcohols and surfactant alcohols via hydroformylation (oxo synthesis) or other functionalization reactions.
• Flavor & Fragrance Industry: Utilized in the synthesis of specific aroma chemicals and flavoring agents that require branched-chain hydrocarbon backbones.
• Research & Development: Employed in academic and industrial R&D for studying polymerization kinetics, catalysis, and material science.

Quality Control

Our 9-Methyl-1-Decene is produced under stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including gas chromatography (GC) for purity and isomer distribution, to ensure it meets precise customer specifications. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming compliance with agreed-upon parameters. We adhere to relevant ISO quality standards to guarantee supply reliability and product consistency for your critical processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat, sparks, and open flame. Recommended storage temperature is 2-25°C. Due to its highly volatile and easily oxidized nature, it is advised to store under an inert atmosphere (e.g., nitrogen) for long-term preservation and to minimize peroxide formation. Keep away from strong oxidizing agents.
