Description

Cycloheptyl Isocyanate CAS NO 4747-68-6 is a versatile organic building block characterized by its seven-membered cycloalkyl ring attached to a highly reactive isocyanate functional group. This compound is critical for introducing the cycloheptyl moiety into advanced chemical architectures, enabling the synthesis of specialized polymers and fine chemicals with tailored properties. It is primarily sought after by R&D chemists and process engineers in the pharmaceutical, agrochemical, and specialty polymer industries for applications requiring specific steric and chemical functionality.

Application

• Pharmaceutical Intermediates: Serves as a key precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly for compounds requiring a bulky, lipophilic cycloheptyl group to modulate bioavailability and receptor binding.
• Agrochemical Synthesis: Used in the production of herbicides, fungicides, and pesticides, where the cycloheptyl ring can contribute to unique biological activity and environmental persistence profiles.
• Polyurethane & Polyurea Production: Acts as a monomer or chain extender in the formulation of high-performance polyurethane elastomers, coatings, and adhesives, imparting flexibility and chemical resistance.
• Specialty Polymer Modifier: Employed to modify the properties of nylons, polyamides, and other engineering plastics, enhancing thermal stability and mechanical strength.
• Cross-linking Agent: Functions as an effective cross-linker for resins and polymers, improving their durability, hardness, and resistance to solvents.
• Chemical Research & Development: A valuable reagent in academic and industrial R&D for exploring new reaction pathways and creating novel heterocyclic or carbamate-based compounds.

Quality Control

Our Cycloheptyl Isocyanate is manufactured under stringent quality management systems. Every batch undergoes comprehensive analytical testing, including GC, HPLC, and IR spectroscopy, to ensure high purity and consistency. We provide detailed Certificates of Analysis (COA) with each shipment, documenting key parameters such as assay, identity, and impurity profiles. Our quality commitment aligns with cGMP principles where applicable, ensuring reliability for your most critical synthesis and production processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 2°C and 8°C (refrigerated) or as specified on the label. Due to its hygroscopic and moisture-sensitive nature, the container must be kept tightly sealed under a dry inert atmosphere (e.g., nitrogen) to prevent hydrolysis and degradation. Keep away from heat, sparks, open flames, and incompatible materials such as alcohols, amines, and strong bases.
