Description

Cyclopropanecarbonyl Chloride, 2-(2-Methyl-1-Propenyl)- (9Ci) is a specialized organic acid chloride building block used in advanced chemical synthesis. This compound matters for its unique cyclopropane and prenyl-like side chain, which introduces significant steric and electronic complexity into target molecules. It is primarily needed by research and development chemists in the pharmaceutical and agrochemical industries for constructing novel active ingredients and intermediates.

Application

• Pharmaceutical Intermediate: A key building block for the synthesis of novel drug candidates, particularly those targeting central nervous system (CNS) disorders and infectious diseases.
• Agrochemical Synthesis: Used in the research and development of new pesticides and herbicides, where the cyclopropane moiety can enhance biological activity and environmental stability.
• Material Science Research: Serves as a monomer or cross-linking agent in the development of specialty polymers with tailored thermal or mechanical properties.
• Chemical Biology Probes: Employed to create activity-based probes (ABPs) or affinity labels for studying enzyme function and target identification.
• Fine Chemical Production: Acts as a precursor for synthesizing complex flavors, fragrances, and other high-value specialty chemicals.

Quality Control

Our Cyclopropanecarbonyl Chloride, 2-(2-Methyl-1-Propenyl)- (9Ci) is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including NMR, HPLC, and GC analysis, to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing all specifications are provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature and reactivity as an acid chloride, store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, and well-ventilated place. Recommended storage temperature is 2-8°C for long-term stability. Keep away from strong bases, alcohols, and water.
