Description

Cyclopentanol, 1-Ethynyl-2-Methoxy-, cis- (9Ci) is a specialized organic compound featuring a cis-configured cyclopentanol ring substituted with an ethynyl and a methoxy group. This unique structure makes it a valuable chiral building block and intermediate in advanced organic synthesis, where precise stereochemistry is critical. It is primarily needed by research and development laboratories, as well as production facilities in the pharmaceutical and fine chemical industries, for the synthesis of complex molecules, including potential active pharmaceutical ingredients (APIs) and novel materials.

Application

• Pharmaceutical Intermediate: Serves as a key chiral synthon in the research and development of new drug candidates, particularly for constructing complex, stereochemically defined molecular architectures.
• Fine Chemical Synthesis: Used as a specialized building block for synthesizing complex natural products, fragrances, and other high-value specialty chemicals.
• Academic & Industrial Research: Employed in methodological studies and process chemistry development for novel synthetic routes involving alkynes and cyclic ethers.
• Material Science Research: Potential precursor for developing novel polymers or ligands with specific steric and electronic properties.
