Description

Cyclopropanecarbonyl Iodide (9Ci) is a versatile and reactive organoiodine compound, serving as a key building block in advanced organic synthesis. Its value lies in the unique reactivity of the cyclopropane ring and the iodide moiety, enabling the introduction of the cyclopropanecarbonyl group into target molecules. This compound is essential for researchers and process chemists in the pharmaceutical, agrochemical, and specialty chemical industries, where it is used to create novel molecular architectures with specific biological or material properties.

Application

• Pharmaceutical Intermediate: A critical reagent for synthesizing active pharmaceutical ingredients (APIs) and drug candidates, particularly those containing cyclopropane motifs known for metabolic stability.
• Agrochemical Synthesis: Used in the production of advanced pesticides and herbicides, where the cyclopropane structure can enhance biological activity and environmental profile.
• Cross-Coupling Reactions: Acts as an electrophilic coupling partner in metal-catalyzed reactions (e.g., Negishi, Kumada) for C-C bond formation.
• Ligand and Catalyst Development: Serves as a precursor for synthesizing specialized ligands and organometallic catalysts.
• Material Science Research: Employed in the synthesis of monomers or functional units for novel polymers and advanced materials.
• Academic & R&D Laboratories: A valuable tool for methodological development and exploring new synthetic pathways in organic chemistry.

Quality Control

Our Cyclopropanecarbonyl Iodide is produced and handled under strict quality management protocols. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. We provide comprehensive Certificates of Analysis (COA) with detailed results from techniques such as NMR, HPLC, and GC. Our quality commitment aligns with cGMP and ISO 9001 principles where applicable, ensuring reliability for your critical R&D and scale-up processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic (moisture-sensitive) nature, the container should be kept sealed under an inert atmosphere (e.g., nitrogen or argon) for long-term storage. Recommended storage temperature is 2-8°C to maximize stability.
