Description

1,3,6-Cycloheptatriene-1-Carbonyl Chloride (6Ci) is a highly reactive and versatile acyl chloride derivative of cycloheptatriene, serving as a critical building block in advanced organic synthesis. Its unique strained-ring structure and reactive carbonyl chloride group make it an invaluable precursor for constructing complex molecular architectures, particularly in pharmaceutical and agrochemical research. This compound is essential for chemists and R&D teams in the fine chemical, pharmaceutical intermediate, and material science sectors seeking to develop novel active ingredients and functional materials.

Application

• Pharmaceutical Intermediate: A key synthon for the synthesis of novel drug candidates, particularly those with complex polycyclic or strained-ring frameworks.
• Agrochemical Research: Used in the development of new pesticides and herbicides, where its reactive site allows for the introduction of specific bioactive moieties.
• Material Science Precursor: Employed in the creation of specialty polymers and advanced organic materials with tailored electronic or structural properties.
• Organic Synthesis Reagent: Acts as an acylating agent to introduce the 1,3,6-cycloheptatriene-1-carbonyl group into target molecules under mild conditions.
• Ligand and Catalyst Development: Useful for synthesizing novel ligands for transition metal catalysis, leveraging the unique coordination geometry of the cycloheptatriene system.
• Academic and R&D Laboratories: A valuable tool for methodological studies and exploring new chemical reactions involving strained, unsaturated systems.

Quality Control

Our 1,3,6-Cycloheptatriene-1-Carbonyl Chloride (6Ci) is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity suitable for research and development applications. While specific grades can be produced, typical quality assurance includes verification of identity, purity, and absence of critical impurities. A comprehensive Certificate of Analysis (COA) detailing specific test results is provided with each shipment to support your quality management system.

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 (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent decomposition. Keep away from heat, sparks, open flames, and incompatible materials such as strong bases, alcohols, and amines.
