Description

(R)-Methyl 2-Phenylpropanoate CAS NO 34083-55-1 is a high-purity chiral ester, specifically the (R)-enantiomer of methyl 2-phenylpropionate. This compound is a critical chiral building block and resolving agent in asymmetric synthesis, valued for its defined stereochemistry which is essential for producing enantiomerically pure pharmaceuticals and fine chemicals. It is primarily needed by research institutions and manufacturers in the pharmaceutical, agrochemical, and advanced material sectors for the development of active pharmaceutical ingredients (APIs), chiral catalysts, and specialty fragrances.

Application

• Chiral Intermediate in Pharmaceutical Synthesis: A key starting material or resolving agent for producing enantiopure non-steroidal anti-inflammatory drugs (NSAIDs) and other active pharmaceutical ingredients.
• Asymmetric Catalysis & Ligand Synthesis: Used in the preparation of chiral ligands and catalysts for stereoselective chemical transformations.
• Agrochemical Research & Development: Serves as a chiral synthon in the creation of enantiomerically pure herbicides, fungicides, and plant growth regulators.
• Flavor and Fragrance Industry: Employed as a precursor for synthesizing specific, high-value chiral aroma compounds.
• Academic & Industrial R&D: A valuable reference standard and building block in methodological development for organic and medicinal chemistry.
• Material Science: Potential use in the synthesis of chiral monomers for advanced polymeric materials.

Quality Control

Our (R)-Methyl 2-Phenylpropanoate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including chiral purity analysis by HPLC or GC, to ensure compliance with exacting standards for research and production use. A comprehensive Certificate of Analysis (COA) detailing identity, purity, enantiomeric excess, and impurity profiles is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). Due to its high volatility, ensure containers are securely sealed when not in use and stored away from heat and open flame. Keep away from strong bases and incompatible materials.
