Description

4-Cyclohexene-1,2-Dicarbonyl Dichloride, cis- (9Ci) CAS NO 41183-19-1 is a versatile and reactive diacid chloride derivative of a partially hydrogenated phthalic acid. This compound serves as a critical high-purity building block for synthesizing complex organic molecules, particularly in advanced pharmaceutical and agrochemical research. It is primarily sought after by R&D chemists and process development scientists in fine chemical and active pharmaceutical ingredient (API) manufacturing. Its cis-configuration and reactive acyl chloride groups make it a valuable precursor for creating specialized polymers, ligands, and functional materials.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of novel drug candidates, especially those requiring a rigid, bicyclic core structure.
• Agrochemical Synthesis: Used in creating advanced herbicides, fungicides, and plant growth regulators with specific stereochemistry.
• Polymer Chemistry: Serves as a monomer or cross-linking agent for producing specialty polyamides, polyimides, and polyester resins with enhanced thermal properties.
• Ligand and Catalyst Development: Precursor for synthesizing chiral ligands and metal-organic frameworks (MOFs) used in asymmetric catalysis.
• Organic Synthesis Research: A valuable reagent in academic and industrial labs for Diels-Alder reactions, nucleophilic acyl substitutions, and other cycloaddition processes.
• Material Science: Used in the development of advanced coatings, adhesives, and electronic materials requiring specific dielectric or mechanical properties.

Quality Control

Our 4-Cyclohexene-1,2-Dicarbonyl Dichloride, cis- is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing to ensure high purity and consistency, meeting the stringent requirements for research and process chemistry. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment. We adhere to cGMP principles where applicable to support our customers in regulated industries.

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 moisture-sensitive (hygroscopic) 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 heat, open flames, and incompatible materials such as strong bases, alcohols, and amines.
