Description

1-Heptene is a valuable linear α-olefin (LAO) characterized by its seven-carbon chain and terminal double bond, making it a versatile building block in organic synthesis and industrial chemistry. Its primary value lies in its role as a key monomer and intermediate for producing polymers, surfactants, and specialty chemicals. This compound is essential for manufacturers and R&D facilities in the petrochemical, polymer, and fine chemical sectors seeking reliable, high-purity intermediates.

Application

• Polymer & Copolymer Production: Serves as a comonomer in the manufacture of linear low-density polyethylene (LLDPE) and high-density polyethylene (HDPE) to modify density and mechanical properties.
• Organic Synthesis Intermediate: Used in hydroformylation (oxo synthesis) to produce C8 aldehydes and alcohols, which are precursors for plasticizers and surfactants.
• Surfactant & Lubricant Additive Synthesis: Acts as a feedstock for producing heptyl derivatives used in detergent alcohols and specialty lubricant formulations.
• Fine Chemical Manufacturing: Employed in alkylation and as a chain extender in the synthesis of various agrochemicals and pharmaceutical intermediates.
• Research & Development: Utilized in catalytic studies, material science research, and as a standard in analytical chemistry.
• Fuel & Additive Component: Can be used in experimental fuel blends and as a precursor for gasoline and diesel additive synthesis.

Quality Control

Our 1-Heptene is produced and handled under stringent quality management protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analysis using techniques including Gas Chromatography (GC) and meets rigorous internal specifications. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile nature, store in a cool, well-ventilated area away from heat, sparks, and open flames. Recommended storage temperature is 2-8°C (cold chain) for long-term stability to minimize evaporation and polymerization risk. Keep away from strong oxidizing agents.
