Description

4,7-Methano-3Ah-Indene-3A-Carbonyl Chloride, Octahydro-, (3Aalpha,4Beta,7Beta,7Aalpha)- (9Ci) is a specialized bicyclic carbonyl chloride derivative, serving as a critical chiral building block in advanced organic synthesis. Its value lies in its rigid, functionalized structure, which enables the precise construction of complex molecular architectures with defined stereochemistry. This high-purity intermediate is essential for researchers and process chemists in the pharmaceutical and agrochemical industries developing novel active ingredients.

Application

• Pharmaceutical Intermediate: Key chiral synthon for the synthesis of complex drug candidates, particularly in central nervous system (CNS) and cardiovascular therapeutic areas.
• Agrochemical Synthesis: Building block for creating novel pesticides and herbicides with enhanced stereospecific activity and environmental profiles.
• Catalyst & Ligand Development: Precursor for synthesizing novel chiral ligands and organocatalysts used in asymmetric synthesis.
• Material Science Research: Intermediate in the development of specialty polymers and advanced organic materials with specific structural properties.
• Fine Chemical Production: Used in custom synthesis and contract manufacturing for high-value, low-volume specialty chemicals.

Quality Control

Every batch of 4,7-Methano-3Ah-Indene-3A-Carbonyl Chloride, Octahydro- is manufactured under strict quality management systems. Our products undergo rigorous analytical testing, including chiral purity analysis, to ensure compliance with exacting customer specifications and industry standards for advanced intermediates. Certificates of Analysis (COA) documenting identity, purity, and impurity profiles are available for every shipment upon request.

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, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent decomposition.
