Description

(E)-2-Octadecenol CAS NO 41207-34-5 is a high-purity, unsaturated long-chain fatty alcohol characterized by its specific (E)-configuration at the double bond. This precise stereochemistry is critical for applications requiring defined molecular interactions, such as in advanced material synthesis and specialty chemical manufacturing. It serves as a valuable intermediate and building block for researchers and industrial chemists in the pharmaceutical, agrochemical, and cosmetic sectors, where its unique structure imparts specific physical and chemical properties to final products.

Application

• Pharmaceutical Intermediate: Used in the synthesis of specialized lipid-based drug delivery systems and active pharmaceutical ingredients (APIs).
• Agrochemical Synthesis: Serves as a key precursor for manufacturing pheromones, plant growth regulators, and other bioactive compounds.
• Cosmetic & Personal Care Ingredients: Employed in the production of esters and emollients for high-end skincare formulations.
• Liquid Crystal & Advanced Material Research: Acts as a chiral dopant or mesogenic unit in the development of liquid crystal displays (LCDs) and organic semiconductors.
• Lubricant & Surfactant Additive: Functions as a precursor for synthesizing specialty surfactants and high-performance lubricant additives.
• Flavor & Fragrance Industry: Utilized in the creation of complex aroma chemicals and fragrance fixatives.
