Description

Cyclohexanecarbonyl Chloride, 4-(1-Methylpropyl)-, cis- (9Ci) is a specialized organic intermediate featuring a cis-configured cyclohexane ring substituted with a butyl group and an acid chloride functional group. This compound matters for its role as a key building block in the synthesis of complex molecules, particularly in the pharmaceutical and agrochemical sectors where precise stereochemistry is critical. It is needed by R&D chemists and process development scientists working on active pharmaceutical ingredients (APIs), advanced crop protection agents, and high-value fine chemicals.

Application

• Pharmaceutical Intermediate: A crucial precursor in the synthesis of chiral drug candidates, especially those targeting central nervous system (CNS) disorders and anti-inflammatory applications.
• Agrochemical Synthesis: Used in the production of advanced herbicides and fungicides where the cis- configuration imparts specific biological activity.
• Ligand and Catalyst Development: Serves as a starting material for creating novel chiral ligands and organocatalysts used in asymmetric synthesis.
• Fine Chemical Production: Employed in the manufacture of specialty chemicals, including flavors, fragrances, and advanced materials requiring specific stereochemistry.
• Academic and Industrial Research: A valuable reagent for methodological development in organic chemistry, particularly in studies involving stereoselective reactions and ring systems.

Quality Control

Our Cyclohexanecarbonyl Chloride, 4-(1-Methylpropyl)-, cis- (9Ci) is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including chiral purity verification by GC or HPLC, to ensure it meets the high standards required for advanced synthetic applications. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment. We support cGMP and ISO 9001 compliant manufacturing for pharmaceutical-grade requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic and moisture-sensitive nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening. Keep away from strong bases, oxidizing agents, and sources of ignition. For long-term storage, consider refrigeration (2-8°C).
