Description

Undec-1-En-3-Ol is a high-purity, unsaturated fatty alcohol with a terminal double bond and a hydroxyl group at the allylic position. This unique molecular structure makes it a valuable versatile intermediate for synthesizing specialty chemicals, including fragrances, flavors, and pharmaceutical actives. It is essential for manufacturers in the aroma chemical, fine chemical, and life science sectors seeking to develop novel compounds with specific olfactory or biological properties.

Application

• Fragrance & Flavor Intermediate: A key building block for the synthesis of musk analogs, green notes, and other complex aroma molecules.
• Pharmaceutical Synthesis: Serves as a chiral precursor or side chain in the development of active pharmaceutical ingredients (APIs).
• Agrochemicals: Used in the research and production of specialized surfactants, adjuvants, and active ingredients.
• Polymer Modification: Acts as a functional monomer or chain transfer agent to introduce hydroxyl functionality and unsaturation into polymers.
• Liquid Crystal & Electronic Materials: Employed as an intermediate for mesogenic compounds and other advanced organic materials.
• Organic Synthesis & Research: A valuable reagent for cross-coupling reactions, hydrofunctionalization, and other catalytic transformations in R&D laboratories.
