Description

Bicyclo[4.1.0]Hept-2-Ene-7-Carbonyl Chloride, (1Alpha,6Alpha,7Alpha)- (9Ci) CAS NO 79616-93-6 is a highly reactive bicyclic organic building block featuring a strained cyclopropane ring fused to a cyclohexene system. This compound is valued for its unique three-dimensional structure and the electrophilic reactivity of its acid chloride functional group, making it a critical intermediate for advanced synthetic chemistry. It is primarily sought by research chemists and process development scientists in the pharmaceutical and agrochemical industries for constructing complex, stereodefined molecular architectures.

Application

• Pharmaceutical Intermediate: Key precursor for synthesizing novel active pharmaceutical ingredients (APIs) with complex polycyclic or strained ring systems, particularly in medicinal chemistry programs targeting CNS and anti-infective therapies.
• Agrochemical Synthesis: Used in the research and development of new generation herbicides and insecticides, where its bicyclic scaffold can contribute to unique biological activity and selectivity.
• Material Science Research: Serves as a monomer or cross-linking agent in the development of specialty polymers with tailored thermal or mechanical properties derived from its rigid, strained structure.
• Organic Synthesis Building Block: Employed in academic and industrial R&D for cycloaddition reactions, ring-opening polymerizations, and as a scaffold for natural product synthesis and methodology development.
• Ligand and Catalyst Development: Utilized to create novel chiral ligands or organocatalysts, leveraging the defined stereochemistry at the 1Alpha, 6Alpha, and 7Alpha positions.

Quality Control

Our Bicyclo[4.1.0]Hept-2-Ene-7-Carbonyl Chloride is produced and handled under strict quality management protocols. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing key parameters such as assay, impurity profile, and stereochemical purity. Our quality systems are designed to support cGMP and ISO standards for advanced chemical intermediates.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic and moisture-sensitive nature, the container should be kept under an inert atmosphere (e.g., nitrogen or argon) after opening. Recommended long-term storage temperature is 2-8°C. Allow the sealed container to reach ambient temperature before opening to prevent moisture condensation.
