Description

1-Cyclopentene-1-Carbonyl Chloride, 2-Cyano- (6Ci) is a highly reactive and versatile chemical intermediate characterized by its cyclopentene backbone, carbonyl chloride functionality, and nitrile group. This unique structure makes it a critical building block for synthesizing complex molecules, particularly in advanced pharmaceutical and agrochemical research. It is primarily sought after by R&D chemists and process development scientists working on novel active ingredients, heterocyclic compounds, and specialized fine chemicals.

Application

• Pharmaceutical Intermediate: Serves as a key precursor in the synthesis of novel drug candidates, especially those containing fused ring systems or specific nitrile pharmacophores.
• Agrochemical Synthesis: Used in the development of advanced pesticides and herbicides, where the cyclopentene ring contributes to biological activity.
• Fine Chemical Production: Acts as a building block for creating complex, high-value specialty chemicals used in materials science and catalysis.
• Academic & Industrial Research: Employed in organic synthesis laboratories for method development and the construction of novel molecular architectures.
• Peptide Mimetic Chemistry: The reactive acid chloride group makes it suitable for introducing the cyclopentene-carbonyl moiety into peptide chains to modify stability and bioactivity.

Quality Control

Our 1-Cyclopentene-1-Carbonyl Chloride, 2-Cyano- (6Ci) is produced under strict quality management protocols to ensure batch-to-batch consistency and high purity for research and development applications. Each lot is analyzed using advanced chromatographic and spectroscopic techniques. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to support your quality assurance and regulatory documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Due to its properties as a strong acid/organic solvent, hygroscopic (moisture-sensitive), and highly volatile nature, 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 extended stability. Keep away from heat, sparks, open flames, and incompatible materials such as bases, alcohols, and amines.
