Description

1-Cyclooctene-1-Carbonyl Chloride (6Ci) is a highly reactive, cyclic acid chloride derivative that serves as a critical building block for advanced organic synthesis. Its value lies in its ability to introduce the strained cyclooctene moiety and a reactive carbonyl chloride group into target molecules, enabling the construction of complex, functionalized intermediates. This compound is essential for researchers and process chemists in the pharmaceutical, agrochemical, and specialty materials sectors who require high-purity, reliable reagents for developing novel active ingredients and functional polymers.

Application

• Pharmaceutical Intermediate: A key synthon for the synthesis of novel drug candidates, particularly those requiring complex, medium-ring carbocyclic structures.
• Agrochemical Synthesis: Used in the research and development of new pesticides and herbicides, where the cyclooctene ring can contribute to unique biological activity.
• Polymer & Material Science: Acts as a monomer or cross-linking agent for creating specialty polymers with specific thermal or mechanical properties.
• Ligand & Catalyst Development: Employed in the preparation of novel ligands for asymmetric catalysis and organometallic complexes.
• Chemical Biology Probes: Useful for modifying peptides, proteins, or other biomolecules to study biological processes or create bioconjugates.
• Academic & Industrial R&D: Serves as a versatile reagent in exploratory chemistry for constructing diverse chemical libraries and novel molecular architectures.

Quality Control

Our 1-Cyclooctene-1-Carbonyl Chloride (6Ci) is manufactured under strict quality management systems. Every batch undergoes comprehensive analytical testing, including chromatographic purity analysis and identity confirmation, to ensure it meets the high standards required for research and industrial synthesis. A detailed Certificate of Analysis (COA) is provided with each shipment, guaranteeing traceability and consistent quality.

Storage

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