Description

(1R*,2S*,5E,9Z)-5,9-Cyclododecadien-1,2-Diol is a high-purity, stereochemically defined diol derivative of cyclododecatriene, serving as a critical chiral building block and intermediate in advanced organic synthesis. Its value lies in the precise spatial orientation of its hydroxyl groups, which enables the stereoselective construction of complex molecular architectures. This compound is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty fragrance industries who require high-quality intermediates for the development of active ingredients and fine chemicals.

Application

• Pharmaceutical Intermediate: A key chiral synthon for the synthesis of novel drug candidates, particularly in creating complex macrocyclic or polycyclic structures.
• Agrochemical Synthesis: Used in the production of advanced, stereospecific pesticides and plant growth regulators.
• Fine Chemical Production: Serves as a precursor for specialty polymers, ligands for catalysis, and high-value aroma chemicals in the fragrance industry.
• Academic & R&D: A valuable reagent for methodological development in organic chemistry, especially in studies involving dihydroxylation and ring-opening reactions.
• Material Science: Potential monomer for the development of novel polyesters or polycarbonates with specific thermal and mechanical properties.
