Description

Benzene, 1-(Cyclohexyloxy)-4-Ethynyl- (9Ci) CAS NO 587854-10-2 is a specialized aromatic ether derivative featuring both a cyclohexyloxy substituent and an ethynyl (acetylene) functional group. This unique bifunctional structure makes it a valuable advanced intermediate for synthesizing complex molecules in pharmaceutical and agrochemical research. It is primarily sought by R&D chemists and process development scientists for constructing novel scaffolds and fine-tuning molecular properties. The compound's distinct reactivity profile enables its use in coupling reactions and as a building block for materials with tailored electronic or steric characteristics.

Application

• Pharmaceutical Intermediate: Serves as a key synthon in the research and development of new active pharmaceutical ingredients (APIs), particularly for constructing complex aromatic ether cores.
• Agrochemical Synthesis: Used in the development of novel herbicides, fungicides, and insecticides where the ethynyl group can be leveraged for further functionalization.
• Material Science Research: Acts as a monomer or precursor in the synthesis of specialized polymers, liquid crystals, or organic electronic materials.
• Cross-Coupling Reactions: The ethynyl group makes it a suitable substrate for Sonogashira and other palladium-catalyzed cross-coupling reactions to create conjugated systems.
• Ligand and Catalyst Development: Utilized in the preparation of novel ligands for catalysis or as a building block for metal-organic frameworks (MOFs).
• Chemical Biology Probes: Employed in the synthesis of molecular probes and tags due to its ability to participate in click chemistry via the alkyne moiety.
