Description

Cyclooctyl Isocyanate 97 is a versatile aliphatic isocyanate monomer characterized by its eight-membered cycloalkyl ring structure. This compound is essential for introducing the robust, hydrophobic cyclooctyl group into polymer backbones, significantly enhancing material properties such as chemical resistance and thermal stability. It is a critical building block for researchers and manufacturers in the pharmaceutical, agrochemical, and advanced materials sectors, where it is used to synthesize specialized polyurethanes, ureas, and other high-performance derivatives.

Application

• Pharmaceutical Intermediate: Serves as a key reagent in the synthesis of active pharmaceutical ingredients (APIs) and drug candidates, particularly those requiring lipophilic character.
• Agrochemical Synthesis: Used to create novel herbicides, fungicides, and pesticides with enhanced environmental stability and efficacy.
• Specialty Polyurethane Production: A monomer for formulating high-performance coatings, adhesives, sealants, and elastomers (CASE) with superior hydrolytic and chemical resistance.
• Polymer Modification: Employed to functionalize polymers and resins, introducing reactive isocyanate groups for cross-linking or further chemical grafting.
• Chemical Research & Development: A valuable scaffold in medicinal chemistry and materials science for exploring new compound libraries and material properties.
• Surface Coating Agent: Imparts durability and adhesion in advanced industrial and automotive coatings.

Quality Control

Our Cyclooctyl Isocyanate 97 is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including chromatography (GC/HPLC) and spectroscopic methods, to ensure it meets the declared 97% minimum purity and stringent impurity profiles. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and safety parameters is provided with each shipment to guarantee traceability and compliance with your research or production standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its moisture-sensitive (hygroscopic) nature, containers must be kept tightly sealed under a dry inert atmosphere (e.g., nitrogen) to prevent degradation from atmospheric moisture. Keep away from heat, open flames, and incompatible materials such as alcohols, amines, and strong bases.
