Description

Cyclohexene, 4-Fluoro-1-Methyl-4-(1-Methylethyl)-, (4S)- (9Ci) is a chiral, fluorinated monoterpene derivative with a defined stereochemistry at the 4-position. This compound serves as a valuable chiral building block and intermediate in advanced organic synthesis, particularly for introducing the fluorinated isopropylcyclohexene moiety. It is primarily needed by pharmaceutical R&D and fine chemical synthesis teams developing novel active ingredients, agrochemicals, and specialty materials where stereochemical control and fluorine incorporation are critical.

Application

• Pharmaceutical Intermediate: A key chiral synthon for the research and development of novel active pharmaceutical ingredients (APIs), especially in therapeutic areas like oncology and CNS disorders.
• Agrochemical Synthesis: Used in the creation of advanced pesticides and herbicides, where the fluorinated cyclohexene structure can enhance biological activity and environmental stability.
• Flavor & Fragrance Chemistry: Acts as a precursor for synthesizing complex terpene-based aroma molecules with modified olfactory properties.
• Material Science Research: Employed in the development of specialty polymers and liquid crystals, where its rigid, fluorinated core can influence material properties.
• Catalyst & Ligand Development: Serves as a starting material for constructing sophisticated chiral ligands used in asymmetric catalysis.
• Chemical Reference Standard: Supplied as a high-purity standard for analytical method development and quality control in related chemical processes.
