Description

9-Dodecenoic Acid, Methyl Ester is a high-purity unsaturated fatty acid methyl ester (FAME) characterized by its terminal double bond. This unique structure makes it a versatile chemical intermediate and building block for synthesizing more complex molecules. It is primarily sought by industries involved in specialty polymer production, lubricant formulation, and the development of fine chemicals and flavor & fragrance ingredients.

Application

• Polymer & Resin Intermediate: Serves as a monomer or co-monomer in the production of specialty polyesters, polyamides, and other polymers, imparting flexibility and specific functional properties.
• Lubricant & Grease Additive: Used as a synthetic base stock or additive component to enhance lubricity, thermal stability, and biodegradability in advanced lubricant formulations.
• Flavor and Fragrance Synthesis: Acts as a key precursor for manufacturing musk-like odorants and other complex aroma chemicals due to its fatty, waxy odor profile.
• Surfactant & Detergent Manufacturing: Utilized in the synthesis of novel surfactants and emulsifiers for personal care and industrial cleaning products.
• Fine Chemical Building Block: The terminal alkene group is a reactive site for further chemical modifications like epoxidation, hydroformylation, or metathesis, enabling the creation of diverse fine chemicals.
• Plasticizer Production: Can be used to develop bio-based plasticizers as alternatives to phthalates for flexible PVC and other polymer applications.

Quality Control

Our 9-Dodecenoic Acid, Methyl Ester is produced under a strict quality management system. Every batch undergoes comprehensive analytical testing, including Gas Chromatography (GC), to ensure high purity and consistent composition. We provide a detailed Certificate of Analysis (COA) with each shipment, documenting key parameters such as assay, identity, and specific impurities. Our quality commitment ensures the material meets the stringent requirements for use as a reliable industrial intermediate.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from strong oxidizing agents, strong acids, and strong bases. For long-term storage, consider under an inert atmosphere (e.g., nitrogen) to minimize potential oxidation.
