Description

Cycloprop[A]Indene-1-Carbonyl Chloride, 1,1A,6,6A-Tetrahydro-, (1Alpha,1Aalpha,6Aalpha)- (9Ci) is a specialized, high-purity organic intermediate featuring a reactive carbonyl chloride group on a fused cyclopropane-indene scaffold. This compound matters for its role as a critical building block in advanced organic synthesis, enabling the introduction of complex, constrained molecular architectures. It is primarily needed by research chemists and process development scientists in the pharmaceutical and agrochemical industries for the synthesis of novel active ingredients and fine chemicals.

Application

• Pharmaceutical Intermediate: Serves as a key precursor in the synthesis of novel drug candidates, particularly those requiring rigid, three-dimensional frameworks for target binding.
• Agrochemical Synthesis: Used in the research and development of new pesticides and herbicides, where its unique structure can contribute to enhanced biological activity and selectivity.
• Material Science Research: Acts as a monomer or cross-linking agent in the development of advanced polymers with specific thermal or mechanical properties.
• Academic & R&D Laboratories: Employed in methodological studies and the construction of complex natural product analogs or molecular probes.
• Fine Chemical Production: Utilized in the custom synthesis of specialty chemicals for electronics, catalysis, or as ligands in asymmetric synthesis.

Quality Control

Our Cycloprop[A]Indene-1-Carbonyl Chloride is manufactured under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and IR spectroscopy, to ensure high purity and consistent identity. Certificates of Analysis (COA) detailing all specifications are available upon request, supporting compliance in regulated research and development environments.

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 properties as a strong acid/organic solvent, hygroscopic (moisture-sensitive), and highly volatile nature, it must be handled under an inert atmosphere (e.g., nitrogen or argon) in a dedicated chemical fume hood. Keep away from heat, sparks, open flames, and incompatible materials such as bases and oxidizing agents.
