Description

9-Dodecenoic Acid, Ethyl Ester is a high-purity unsaturated fatty acid ester, a key intermediate in fine chemical synthesis. Its terminal double bond offers a versatile reactive site for functionalization, making it valuable for creating specialized polymers, lubricant additives, and bioactive compounds. This product is essential for R&D chemists and manufacturers in the fragrance, pharmaceutical, and advanced materials industries seeking to develop novel, performance-driven molecules.

Application

• Fragrance and Flavor Intermediate: Serves as a building block for synthesizing musky, fruity, or waxy aroma chemicals.
• Polymer Modification: Used as a comonomer or cross-linking agent to introduce flexibility and specific functional groups into polymer chains.
• Lubricant and Fuel Additive Synthesis: A precursor for creating esters that improve viscosity index, low-temperature performance, and anti-wear properties.
• Pharmaceutical and Agrochemical Intermediates: Provides the carbon backbone for synthesizing more complex bioactive molecules and active ingredients.
• Surface Active Agent (Surfactant) Production: Used in the manufacture of specialized, olefin-derived surfactants and emulsifiers.
• Organic Synthesis Reagent: Acts as a versatile starting material or chain extender in various organic transformations, including metathesis and hydroformylation reactions.
