Cyclooctene (COE)

Cyclooctene (COE)

Cyclooctene is a singly unsaturated, eight‑membered cyclic hydrocarbon valued for its balanced reactivity and structural stability. Its internal double bond enables precise functionalization, making it a preferred intermediate for polymers, specialty chemicals, and advanced materials.
Widely used as the feedstock for metathesis polymerization to produce polyoctenamer rubber, cyclooctene also serves as a reliable building block for fragrance ingredients, functional intermediates, and high‑value synthesis pathways. With consistent quality and predictable performance, it provides a dependable C8 platform for innovation.

Applications:

Rubber | polymer crosslinkers | functional intermediates | fragrance | specialty chemicals

Industry:

Rubber, polymers, fragrances, specialty chemicals, petrochemicals
