Description

2-Cyclohexen-1-Ol,2,4-Dimethyl-1-(1-Methylethyl)-,(1R,4R)-(9Ci) is a high-purity, stereochemically defined terpene alcohol derivative, serving as a critical chiral building block and intermediate in advanced organic synthesis. Its defined stereochemistry at the 1R,4R positions provides precise control over the three-dimensional structure of target molecules, which is essential for developing compounds with specific biological activity or material properties. This compound is particularly valuable for R&D and production in the pharmaceutical, agrochemical, and specialty fragrance industries, where the creation of enantiomerically pure products is paramount. CAS number 212559-43-8.

Application

• Pharmaceutical Intermediate: A key chiral synthon for the synthesis of complex drug candidates, particularly in the development of anti-inflammatory, antiviral, or central nervous system (CNS) active compounds.
• Agrochemical Synthesis: Used in the production of enantiomerically pure pesticides and herbicides, where the specific stereochemistry can significantly influence biological efficacy and environmental safety.
• Advanced Material Precursor: Serves as a building block for chiral ligands, catalysts, or monomers used in asymmetric synthesis and the creation of specialty polymers.
• Fragrance & Flavor Chemistry: Acts as an intermediate for synthesizing high-value, nature-identical terpenoid aroma chemicals with specific olfactory profiles.
• Academic & Industrial Research: A valuable reference standard and starting material for methodological development in organic chemistry and catalysis studies.
