Description

4-(Octyloxy)Phenyl Isocyanate is a specialized aromatic isocyanate monomer featuring a long-chain octyloxy substituent. This unique structure provides enhanced hydrophobicity and compatibility with various polymer systems, making it a valuable building block for high-performance materials. It is primarily sought after by R&D chemists and production engineers in the polymer and specialty chemical industries for creating tailored polyurethanes, coatings, and adhesives with specific properties.

Application

• Polymer Synthesis: A key monomer for producing specialized polyurethanes (PUs) and polyurea elastomers with improved flexibility, water resistance, and chemical stability.
• Advanced Coatings & Adhesives: Used in formulating high-performance, moisture-curing coatings, sealants, and adhesives for automotive, marine, and industrial applications.
• Surface Modification: Acts as a coupling agent or surface modifier to introduce isocyanate functional groups onto materials, enhancing adhesion to substrates like glass, metals, and fibers.
• Pharmaceutical & Agrochemical Intermediates: Serves as a critical building block in the synthesis of more complex molecules for active pharmaceutical ingredients (APIs) and agrochemicals.
• Cross-linking Agent: Employed to cross-link polymers containing hydroxyl or amine groups, improving the thermal and mechanical properties of the final product.
• Material Science Research: Utilized in academic and industrial R&D for developing novel polymers, dendrimers, and smart materials with specific functional characteristics.

Quality Control

Every batch of 4-(Octyloxy)Phenyl Isocyanate is manufactured and tested under a strict quality management system. We ensure high purity and consistency through advanced analytical techniques including HPLC, GC, and NMR. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided with each shipment to guarantee compliance with your specific research or production requirements.

Storage

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