Description

2-Furancarboxylic Acid, 2,5-Dihydro-, Methyl Ester, (+)- (9Ci) is a chiral, non-racemic derivative of 2,5-dihydrofuran, characterized by its specific stereochemistry and ester functionality. This compound matters as a valuable chiral building block and intermediate in the synthesis of complex molecules, offering precise control over stereochemistry in the final product. It is needed by research and development chemists in the pharmaceutical and agrochemical industries for applications in asymmetric synthesis, as well as by manufacturers of specialty chemicals and advanced materials.

Application

• Pharmaceutical Intermediate: A key chiral synthon for the research and development of active pharmaceutical ingredients (APIs), particularly in the synthesis of enantiomerically pure drugs.
• Agrochemical Synthesis: Used in the production of chiral pesticides, herbicides, and plant growth regulators where specific stereochemistry is crucial for biological activity.
• Asymmetric Catalysis: Serves as a ligand precursor or a chiral auxiliary in catalytic systems designed for enantioselective transformations.
• Fine Chemical Production: Employed in the manufacture of specialty flavors, fragrances, and other high-value fine chemicals requiring defined stereochemistry.
• Academic & Industrial Research: A valuable tool for methodological development in organic synthesis and for studying structure-activity relationships (SAR).
• Material Science: Potential use as a monomer or precursor for chiral polymers and advanced functional materials.
