Description

(E,Z) 3,13-Octadecadiene-1-Ol CAS NO 66410-28-4 is a high-purity, long-chain unsaturated fatty alcohol with a specific diene structure, serving as a critical intermediate in the synthesis of complex organic molecules. Its defined geometric isomerism (E,Z) is essential for applications requiring precise stereochemistry, such as in the production of insect pheromones and other bioactive compounds. This compound is primarily sought by manufacturers in the agrochemical, flavor & fragrance, and advanced organic synthesis sectors for its role as a key chiral building block.

Application

• Agrochemical Synthesis: A key precursor in the industrial-scale production of specific lepidopteran insect sex pheromones for integrated pest management (IPM) solutions.
• Flavor & Fragrance Industry: Used as an intermediate for synthesizing aroma chemicals that contribute to green, waxy, or fatty olfactory notes in fine perfumery and flavorings.
• Organic Synthesis: Serves as a versatile chiral synthon for pharmaceutical research and the development of other specialty chemicals, leveraging its diene and alcohol functionalities.
• Biochemical Research: Employed in studies of insect behavior and communication as a standard or component in pheromone blends.
• Material Science: Potential monomer or modifier in the synthesis of specialty polymers with unique properties derived from its long aliphatic chain.
