Description

Cyclohexanol, 5-Methyl-2-(1-Methylethyl)-, (2R,5S)-Rel- (9Ci) is a high-purity, stereochemically defined terpene alcohol derivative, serving as a critical chiral intermediate and building block in advanced organic synthesis. Its defined stereochemistry at the 2R and 5S positions makes it invaluable for producing enantiomerically pure compounds where spatial orientation is crucial for biological activity or material properties. This compound is primarily sought by research institutions and industrial manufacturers in the pharmaceutical, agrochemical, and specialty fragrance sectors for the development of novel active ingredients and high-value fine chemicals.

Application

• Pharmaceutical Intermediate: A key chiral synthon for the synthesis of complex drug molecules, particularly in antiviral, anti-inflammatory, and central nervous system (CNS) active pharmaceutical ingredients (APIs).
• Agrochemical Synthesis: Used in the research and production of enantiomerically pure pesticides and herbicides, where specific stereochemistry can enhance efficacy and reduce environmental impact.
• Advanced Material Precursor: Serves as a building block for chiral ligands, catalysts, and monomers used in asymmetric synthesis and the creation of specialty polymers.
• Fragrance & Flavor Chemistry: Acts as a starting material or modifier for synthesizing high-value, stereospecific aroma chemicals with unique olfactory profiles.
• Academic & Industrial Research: A valuable reference standard and reagent in methodological development for stereoselective synthesis and catalysis studies.
