Description

Cyclopentadecene is a high-purity, unsaturated macrocyclic hydrocarbon with significant value as a versatile chemical intermediate. Its unique 15-membered ring structure containing a double bond makes it a crucial building block for synthesizing complex fragrance compounds and specialty polymers. This product is essential for manufacturers in the fragrance, flavor, and advanced materials industries seeking to create musky odorants, macrocyclic lactones, or specialized polymer precursors.

Application

• Fragrance & Flavor Industry: A key intermediate for the synthesis of high-value macrocyclic musk compounds such as muscone and civetone, prized for their warm, animalic, and long-lasting scent profiles.
• Specialty Polymer Production: Serves as a monomer or co-monomer for creating polymers with unique ring structures, potentially offering specific mechanical or thermal properties for niche applications.
• Organic Synthesis & Research: Used as a starting material or intermediate in organic chemistry research and development for constructing complex natural product analogs and novel chemical entities.
• Pharmaceutical Intermediates: Potential use in the synthesis of pharmacologically active macrocyclic compounds, where the ring size and olefin functionality are critical for biological activity.
• Lubricant & Additive Formulation: Can be investigated as a base fluid or additive component in specialty lubricants due to its hydrocarbon structure and potential for functionalization.

Quality Control

Our Cyclopentadecene is produced and tested under a stringent quality management system to ensure batch-to-batch consistency and high purity. We provide comprehensive analytical data, including Gas Chromatography (GC) for purity and isomer distribution, to meet the exacting requirements of fragrance and fine chemical synthesis. A Certificate of Analysis (COA) detailing all specifications is available for every shipment upon request.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its sensitivity to oxidation, minimize headspace and exposure to air after opening.
