Description

(R)-3-Acetoxy-γ-Butyrolactone is a high-purity chiral intermediate and building block of significant importance in asymmetric synthesis. Its value lies in its well-defined stereochemistry, which is crucial for producing enantiomerically pure active pharmaceutical ingredients (APIs) and other fine chemicals. This compound is primarily needed by research institutions and manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries for the development of novel therapeutic agents and advanced materials.

Application

• Pharmaceutical Intermediate: A key chiral synthon in the synthesis of enantiomerically pure drugs, particularly in central nervous system (CNS) and cardiovascular research.
• Asymmetric Synthesis: Serves as a versatile building block for constructing complex molecular architectures with defined stereocenters.
• Agrochemical Development: Used in the research and production of chiral pesticides and herbicides where specific stereochemistry affects biological activity.
• Fine Chemical Production: Employed in the manufacture of specialty chemicals, flavors, and fragrances requiring high enantiomeric purity.
• Academic & Industrial R&D: A valuable reagent for methodological development in organic chemistry and catalysis studies.
