Description

4-Undecen-1-ol, (E)- is a high-purity, unsaturated fatty alcohol characterized by its specific cis-trans isomerism. This compound is valued for its role as a versatile chemical intermediate and a building block for synthesizing more complex molecules, including flavors, fragrances, and specialty polymers. It is essential for R&D chemists and production teams in the fragrance, flavor, and fine chemical industries seeking to create unique organoleptic profiles or advanced material properties.

Application

• Fragrance and Flavor Intermediate: A key building block for the synthesis of novel aroma chemicals and flavoring agents, contributing green, waxy, or citrus-like notes.
• Specialty Polymer Synthesis: Used in the production of polyesters, polyurethanes, and other polymers where the terminal double bond and hydroxyl group enable cross-linking or introduce specific functionalities.
• Lubricant and Surfactant Additive: Serves as a precursor for ester-based lubricants and non-ionic surfactants, enhancing performance characteristics.
• Organic Synthesis Reagent: Employed in research and development for carbon chain elongation, Grignard reactions, and other fine chemical syntheses.
• Pharmaceutical Intermediates: Acts as a chiral synthon in the multi-step synthesis of active pharmaceutical ingredients (APIs) and other bioactive compounds.
