Description

Cyclopentanecarboxylic Acid, 1-Hydroxy-2-Methyl-, Methyl Ester (9Ci) is a high-purity, functionalized cyclopentane derivative that serves as a versatile chiral building block and intermediate in advanced organic synthesis. Its value lies in its unique sterically constrained cyclopentane ring and the presence of both ester and hydroxyl functional groups, which enable precise chemical modifications. This compound is essential for researchers and manufacturers in the pharmaceutical and agrochemical industries, particularly for developing novel active ingredients and fine chemicals.

Application

• Pharmaceutical Intermediate: A key chiral synthon for the synthesis of complex drug molecules, including potential antiviral, anti-inflammatory, or central nervous system (CNS) agents.
• Agrochemical Synthesis: Used in the research and development of new herbicides, fungicides, or plant growth regulators that require specific stereochemistry.
• Fine Chemical Production: Serves as a precursor for flavors, fragrances, and other specialty chemicals where the cyclopentane structure imparts desired olfactory or flavor profiles.
• Academic & R&D: A valuable reagent in organic chemistry research for methodology development, catalysis studies, and exploring new reaction pathways with sterically defined substrates.
• Material Science: Potential monomer or cross-linking agent in the synthesis of specialized polymers with tailored thermal or mechanical properties.
