Description

Cyclohexanecarbonyl Chloride, 2-Ethenyl-, trans- (9Ci) is a specialized organic intermediate featuring a reactive acid chloride group and a vinyl substituent on a cyclohexane ring. This unique structure makes it a valuable building block for synthesizing complex molecules in advanced research and development. It is primarily sought after by pharmaceutical, agrochemical, and fine chemical manufacturers for constructing novel active ingredients and functional materials.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of novel drug candidates, particularly those requiring a functionalized cyclohexane scaffold.
• Agrochemical Synthesis: Used in the development of advanced herbicides, fungicides, and plant growth regulators.
• Polymer Chemistry: Serves as a monomer or cross-linking agent for specialty polymers with tailored thermal or mechanical properties.
• Liquid Crystal & OLED Materials: Building block for creating advanced organic electronic materials and display components.
• Organic Synthesis & Catalysis: Versatile reagent for introducing the trans-2-vinylcyclohexanecarbonyl moiety into target molecules via acylations or further functionalizations.
• Flavor & Fragrance Industry: Intermediate for the production of complex synthetic musks and other aroma chemicals.

Quality Control

Our Cyclohexanecarbonyl Chloride, 2-Ethenyl-, trans- (9Ci) is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including GC, HPLC, and NMR, to ensure high chemical purity and isomeric consistency. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at 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, oxidizers, and sources of ignition.
