Description

Cyclopentanecarbonyl Chloride, 3,4-Dichloro- (9Ci) CAS NO 56447-17-7 is a specialized chlorinated acid chloride derivative of cyclopentane, serving as a critical high-purity building block in advanced organic synthesis. Its value lies in its dual reactive sites—the acid chloride group and the dichloro-substituted ring—which enable precise molecular construction for complex target molecules. This intermediate is essential for researchers and process chemists in the pharmaceutical and agrochemical industries developing novel active ingredients, where reliable quality and consistent supply are paramount.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of novel drug candidates, particularly in creating complex carbocyclic and heterocyclic scaffolds.
• Agrochemical Synthesis: Used in the research and production of advanced herbicides, fungicides, and insecticides requiring specific chlorinated ring systems.
• Material Science Research: Serves as a monomer or cross-linking agent in the development of specialized polymers with unique thermal or chemical resistance properties.
• Fine Chemical Production: Employed in custom synthesis and contract manufacturing for producing high-value, low-volume specialty chemicals.
• Academic & R&D: A valuable reagent for methodological studies in organic chemistry, including new coupling reactions and catalysis research.

Quality Control

Our Cyclopentanecarbonyl Chloride, 3,4-Dichloro- (9Ci) is manufactured under stringent quality management systems. Each batch undergoes rigorous analytical testing, including chromatography (HPLC/GC) and spectroscopic methods (IR, NMR), to ensure high purity and batch-to-batch consistency essential for sensitive synthetic applications. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to support your quality assurance and regulatory documentation.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place away from incompatible materials such as strong bases, alcohols, and amines. Due to its nature as a strong acid/organic solvent, it should be handled in a controlled environment. Recommended storage temperature is 2-8°C for long-term stability. Keep container tightly sealed when not in use to prevent moisture absorption and decomposition.
