Description

1-Cycloheptene-1-Carbonyl Chloride (6Ci,9Ci) is a highly reactive, seven-membered cyclic acid chloride derivative, serving as a critical building block for introducing the strained cycloheptene moiety into more complex molecular architectures. Its value lies in its ability to act as an acylating agent or a precursor for further functionalization under mild conditions, enabling the synthesis of novel compounds with specific ring structures. This intermediate is primarily needed by research and development chemists in the pharmaceutical and agrochemical industries for creating new active ingredients, as well as by material scientists exploring advanced polymers and specialty chemicals.

Application

• Pharmaceutical Intermediate: Key synthon for the development of novel drug candidates, particularly those requiring a seven-membered carbocyclic or heterocyclic framework.
• Agrochemical Synthesis: Used in the research and production of advanced pesticides and herbicides where the cycloheptene structure imparts specific biological activity.
• Material Science Research: Serves as a monomer or cross-linking agent in the development of specialty polymers with unique thermal or mechanical properties.
• Organic Synthesis & Catalysis: Employed in academic and industrial R&D for constructing complex natural products or as a ligand precursor in catalytic systems.
• Fine Chemical Production: Integral for manufacturing custom-designed fragrance compounds, dyes, and other high-value specialty chemicals.

Quality Control

Our 1-Cycloheptene-1-Carbonyl Chloride is produced and handled under strict quality management protocols to ensure batch-to-batch consistency and high purity, essential for sensitive synthetic applications. Each lot undergoes comprehensive analytical characterization, including chromatographic purity assays and spectroscopic identification. Certificates of Analysis (COA) detailing specific results are provided with every shipment to support your quality assurance and regulatory documentation needs.

Storage

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