Description

Propanoic Acid, 2-(Acetyloxy)-, 1,1-Dimethylethyl Ester, (R)- (9Ci) is a chiral, optically active ester derivative of propanoic acid, serving as a critical chiral building block and protecting group reagent in advanced organic synthesis. Its value lies in enabling the stereoselective construction of complex molecules, ensuring high enantiomeric purity in final products. This compound is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries who require high-purity chiral intermediates for developing active ingredients and fine chemicals.

Application

• Pharmaceutical Intermediate: A key chiral synthon in the asymmetric synthesis of active pharmaceutical ingredients (APIs), particularly for central nervous system (CNS) drugs and anti-inflammatory agents.
• Agrochemical Synthesis: Used in the production of enantiomerically pure herbicides, fungicides, and pesticides where specific stereochemistry is crucial for bioactivity.
• Asymmetric Catalysis Research: Employed as a ligand precursor or a test substrate in the development and screening of novel chiral catalysts.
• Fine Chemical Production: Serves as a building block for synthesizing specialty chemicals, flavors, and fragrances that require specific stereochemical configurations.
• Academic & R&D Laboratories: Utilized in methodological studies and process chemistry research for exploring new synthetic routes.
