Description

3-Oxabicyclo[3.2.0]Heptane-2-Carboxylicacid,Methylester,(1R,2R,5S)-(9Ci) is a high-purity, stereochemically defined bicyclic lactone derivative that serves as a critical chiral building block in advanced organic synthesis. Its unique fused oxabicyclic structure makes it a valuable intermediate for constructing complex molecules with precise three-dimensional architecture. This compound is essential for research and development chemists in the pharmaceutical and agrochemical industries, particularly for the synthesis of novel active ingredients and fine chemicals where stereochemical control is paramount.

Application

• Pharmaceutical Intermediate: A key chiral synthon for the development of new active pharmaceutical ingredients (APIs), especially in antiviral, antibacterial, and central nervous system (CNS) drug candidates.
• Agrochemical Synthesis: Used in the research and production of advanced pesticides and herbicides where its bicyclic framework contributes to biological activity.
• Asymmetric Catalysis & Ligand Design: Serves as a precursor for novel chiral ligands and catalysts used in enantioselective transformations.
• Fine Chemical & Flavor/Fragrance Intermediate: Employed in the synthesis of complex, high-value specialty chemicals and aroma compounds.
• Academic & Industrial R&D: A valuable tool for methodological development in organic chemistry and for exploring new chemical spaces in material science.

Quality Control

Every batch of our 3-Oxabicyclo[3.2.0]Heptane-2-Carboxylicacid,Methylester,(1R,2R,5S)-(9Ci) is produced and tested under a strict quality management system to ensure identity, purity, and stereochemical integrity. We provide comprehensive analytical data, including chiral purity verification by HPLC. Certificates of Analysis (COA) detailing specific batch results are available upon request, supporting your regulatory and R&D documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
