Description

Cyclohexanecarbonyl Chloride, 4-Ethyl-, trans- (9Ci) is a specialized organic intermediate featuring a trans-configured ethyl group on the cyclohexane ring. This compound matters for its role as a key acylating agent and building block in the synthesis of complex molecules, where its stereochemistry and functional group are critical for achieving desired product profiles. It is primarily needed by research and development chemists and process engineers in the pharmaceutical, agrochemical, and advanced materials sectors for creating novel active ingredients and functional polymers.

Application

• Pharmaceutical Intermediate: Serves as a crucial precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly for compounds requiring a stereodefined cyclohexane carboxylic acid derivative.
• Agrochemical Synthesis: Used in the production of herbicides, fungicides, and plant growth regulators where the 4-ethyl-trans-cyclohexane moiety imparts specific biological activity.
• Liquid Crystal & Advanced Material Production: Acts as a building block for mesogens and other organic electronic materials due to its rigid, substituted cyclohexyl structure.
• Organic Synthesis & Research: Employed as a versatile acyl chloride reagent in academic and industrial laboratories for amide bond formation, esterification, and Friedel-Crafts acylation reactions.
• Fragrance & Flavor Chemistry: Utilized in the controlled synthesis of aroma chemicals and flavorants that benefit from the specific structural characteristics of this intermediate.
• Polymer Modification: Can be used to introduce functional cyclohexyl groups into polymer chains to alter physical properties like thermal stability and solubility.

Quality Control

Our production of Cyclohexanecarbonyl Chloride, 4-Ethyl-, trans- (9Ci) adheres to stringent quality protocols to ensure batch-to-batch consistency and reliability for your synthetic processes. All materials undergo rigorous analytical testing, including chromatography (GC/HPLC) and spectroscopic methods (NMR, IR), to confirm identity, purity, and isomeric composition. Certificates of Analysis (COA) detailing all specifications are provided with each shipment, and we support compliance with relevant regulatory frameworks for industrial and research use.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (typically 15-25°C). Due to its hygroscopic and moisture-sensitive nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent hydrolysis. Keep away from strong bases, oxidizing agents, and sources of ignition.
