Description

(4R)-1-Methyl-4-(1-Methylethenyl)-2-Cyclohexen-1-Ol is a chiral, monoterpenoid alcohol with a distinct cyclohexene backbone. This compound matters as a versatile chiral building block and intermediate, prized for its defined stereochemistry which is critical for synthesizing high-value, optically active molecules. It is needed by research and development chemists in the pharmaceutical and agrochemical industries, as well as by manufacturers of specialty fragrances and flavors seeking to create novel organoleptic profiles.

Application

• Pharmaceutical Intermediate: Serves as a key chiral synthon in the synthesis of active pharmaceutical ingredients (APIs), particularly for compounds requiring specific stereocenters.
• Agrochemical Synthesis: Used in the research and production of advanced pesticides and herbicides where stereoselectivity influences biological activity.
• Fragrance & Flavor Ingredient: Acts as a precursor for novel terpene-based aroma chemicals, contributing woody, green, or citrus notes in fine perfumery and flavor formulations.
• Organic Synthesis Research: Employed in academic and industrial R&D for methodological studies in asymmetric synthesis, cycloadditions, and natural product synthesis.
• Specialty Chemical Manufacturing: Functions as an intermediate for producing other high-value fine chemicals, including catalysts and ligands for asymmetric catalysis.
