Description

Butanoic Acid, (2R)-2-Pyrrolidinyl Ester (9Ci) is a specialized chiral ester of butanoic acid, serving as a high-value building block in advanced organic synthesis. Its precise stereochemistry makes it a critical intermediate for the development of enantiomerically pure pharmaceuticals and fine chemicals. This compound is essential for research and production chemists in the pharmaceutical, agrochemical, and specialty chemical industries seeking to introduce chiral complexity into target molecules.

Application

• Pharmaceutical Intermediate: A key chiral synthon for the synthesis of active pharmaceutical ingredients (APIs), particularly in the development of neurologically active compounds and receptor modulators.
• Asymmetric Synthesis: Utilized as a chiral auxiliary or precursor in stereoselective reactions to construct complex molecular architectures with high enantiomeric excess.
• Agrochemical Research: Employed in the development of novel, enantiomerically pure pesticides and herbicides where specific stereochemistry is crucial for biological activity.
• Flavor & Fragrance Chemistry: Serves as a precursor for the synthesis of chiral flavoring agents and aroma chemicals, contributing to nuanced sensory profiles.
• Academic & Industrial R&D: Used in methodological research for new catalytic processes and as a standard in analytical method development for chiral separation techniques.
