Description

Cyclohexanecarbonyl Chloride, 4-(1-Methylpropyl)-, trans- (9Ci) is a specialized organic intermediate featuring a sterically defined trans-cyclohexane ring substituted with a sec-butyl group and an acid chloride functional group. This compound matters for its role as a key chiral building block in the synthesis of complex molecules, where its defined stereochemistry and reactive acyl chloride group enable precise chemical transformations. It is primarily needed by research and development chemists in the pharmaceutical and agrochemical industries for creating novel active ingredients, as well as by fine chemical manufacturers producing advanced materials and catalysts.

Application

• Pharmaceutical Intermediate: A critical chiral synthon for the research and development of new active pharmaceutical ingredients (APIs), particularly in therapeutic areas requiring stereochemical purity.
• Agrochemical Synthesis: Used in the production of advanced pesticides and herbicides where the specific stereochemistry of the molecule can influence biological activity.
• Ligand and Catalyst Preparation: Serves as a precursor for synthesizing specialized ligands used in asymmetric catalysis and organometallic chemistry.
• Fine Chemical and Material Science: Employed in the development of performance chemicals, liquid crystals, and other advanced organic materials.
• Academic and Industrial Research: A valuable reagent for methodological studies in organic synthesis, particularly in reactions involving acyl chlorides and stereoselective processes.

Quality Control

Our production of Cyclohexanecarbonyl Chloride, 4-(1-Methylpropyl)-, trans- (9Ci) adheres to stringent quality management protocols. Every batch undergoes rigorous analytical testing, including chiral purity analysis, to ensure it meets the high standards required for advanced synthetic applications. Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are available upon request, providing full traceability and compliance documentation for your quality systems.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic and moisture-sensitive nature, the container must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis. Recommended storage temperature is 2-8°C for long-term stability. Keep away from strong bases, oxidizing agents, and sources of ignition.
