Description

Cyclopropaneacetaldehyde, 2-Acetyl-, (1R,2R)- (9Ci) is a high-purity chiral building block of significant interest in advanced organic synthesis. This compound matters for its role as a key intermediate in the production of complex, stereochemically defined molecules, particularly in the pharmaceutical sector. It is needed by R&D chemists and process development scientists working on novel active pharmaceutical ingredients (APIs), agrochemicals, and specialty fine chemicals where precise stereochemistry is critical for biological activity.

Application

• Pharmaceutical Intermediate: A crucial chiral synthon for the synthesis of novel drug candidates, particularly in central nervous system (CNS) and antiviral research.
• Agrochemical Synthesis: Used in the development of advanced pesticides and herbicides with specific stereoisomeric activity.
• Asymmetric Catalysis Research: Serves as a substrate or ligand precursor in the development of new catalytic systems for stereoselective reactions.
• Fine Chemical Production: Employed in the manufacture of complex fragrance and flavor molecules requiring specific enantiomeric purity.
• Academic & Industrial R&D: A valuable tool for methodological studies in organic chemistry, particularly in cyclopropane and aldol chemistry.

Quality Control

Our Cyclopropaneacetaldehyde, 2-Acetyl-, (1R,2R)- (9Ci) is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including chiral HPLC for enantiomeric excess (ee) and GC/HPLC for chemical purity, to ensure it meets the high standards required for pharmaceutical R&D. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and chiral purity is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at controlled room temperature (15-25°C) in a cool, dry, and well-ventilated place. Due to its sensitivity to oxidation, the container should be kept sealed under positive pressure of inert gas after opening.
