Description

Cyclohexanecarboxaldehyde, 1-Methyl-3-Oxo-, (R)- (9Ci) is a high-value chiral aldehyde building block, specifically the (R)-enantiomer, which is critical for introducing stereochemical complexity into target molecules. Its unique structure, featuring both an aldehyde and a ketone functional group on a substituted cyclohexane ring, makes it an indispensable intermediate in asymmetric synthesis. This compound is primarily sought after by research institutions and pharmaceutical companies engaged in the development of novel active pharmaceutical ingredients (APIs), agrochemicals, and advanced materials where precise stereocontrol is paramount.

Application

• Pharmaceutical Intermediate: A key chiral synthon for the synthesis of complex drug candidates, particularly in therapeutic areas requiring high enantiomeric purity.
• Agrochemical Research: Used in the development of enantiomerically pure pesticides and herbicides, where the biological activity is often specific to one stereoisomer.
• Asymmetric Catalysis: Serves as a sophisticated substrate or ligand precursor in catalytic reactions to create other chiral molecules.
• Flavor & Fragrance Chemistry: Potential intermediate for creating stereodefined aroma chemicals and specialty odorants.
• Material Science: Building block for synthesizing chiral polymers or liquid crystals with specific optical properties.
• Academic & Process Chemistry: Used in methodological studies and scale-up process development for chiral molecule manufacturing.

Quality Control

Every batch of our Cyclohexanecarboxaldehyde, 1-Methyl-3-Oxo-, (R)- (9Ci) is produced and tested under strict quality management systems. We provide comprehensive analytical data to ensure it meets the exacting standards required for advanced synthetic applications. A detailed Certificate of Analysis (COA) is supplied with each shipment, reporting critical parameters such as chiral purity (enantiomeric excess), chemical purity, and identity confirmation. Our quality commitment supports compliance in cGMP and ISO 9001 environments for research and development use.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry place at 2-8°C for long-term stability. This compound is easily oxidized and light-sensitive; prolonged exposure to air, moisture, or light should be avoided to maintain purity and prevent degradation. Allow the container to reach room temperature before opening to minimize moisture condensation.
