Description

Cyclopentanecarbonyl Bromide (6Ci) is a versatile and reactive organic bromide derivative, serving as a crucial acylating agent and building block in advanced chemical synthesis. Its value lies in providing a cyclopentane-based carbonyl bromide moiety, enabling the introduction of functionalized cyclopentyl groups into target molecules with high precision. This compound is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries, particularly for developing novel active ingredients and complex intermediates.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of active pharmaceutical ingredients (APIs) containing cyclopentane rings, such as certain protease inhibitors and other bioactive molecules.
• Agrochemical Synthesis: Used in the production of advanced pesticides and herbicides where the cyclopentyl group contributes to specific biological activity and stability.
• Organic Synthesis Reagent: Acts as a versatile acyl bromide reagent for Friedel-Crafts acylation, esterification, and amide coupling reactions in research and development.
• Material Science Precursor: Employed in the synthesis of specialized polymers, ligands for catalysis, and other functional materials requiring tailored cyclopentane-based structures.
• Chemical Research: Serves as a standard or starting material in methodological studies and for creating compound libraries in medicinal chemistry.

Quality Control

Our Cyclopentanecarbonyl Bromide is produced under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC, GC, NMR, and IR spectroscopy, to verify identity, purity, and consistency. We provide a detailed Certificate of Analysis (COA) with every shipment, ensuring full traceability and compliance with your research or production specifications. Our commitment is to deliver material of the highest reliability for critical synthetic applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (typically 15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Keep away from heat, sparks, open flames, and incompatible materials such as strong bases and oxidizing agents.
