Description

3-Isocyanato-4-Methoxybiphenyl 97 is a specialized aromatic isocyanate intermediate used in the synthesis of advanced polymers and fine chemicals. Its value lies in its unique bifunctional structure, combining a reactive isocyanate group with a methoxy-substituted biphenyl core, which enables the creation of materials with tailored thermal and mechanical properties. This compound is essential for R&D and production chemists in the pharmaceutical, agrochemical, and high-performance polymer industries, particularly for developing novel polyurethanes, coatings, and active pharmaceutical ingredients (APIs).

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of novel drug candidates and active pharmaceutical ingredients (APIs).
• Agrochemical Synthesis: Used in the research and production of advanced pesticides and herbicides.
• Polymer & Polyurethane Production: Serves as a core monomer for developing specialized polyurethane elastomers, coatings, and adhesives with enhanced properties.
• Liquid Crystal & Electronic Materials: A precursor in the manufacture of liquid crystal displays (LCDs) and other electronic materials.
• Cross-linking Agent: Functions as a reactive cross-linker in resin and polymer systems to improve durability and chemical resistance.
• Research & Development: A valuable reagent for academic and industrial R&D in organic and medicinal chemistry.

Quality Control

Our 3-Isocyanato-4-Methoxybiphenyl 97 is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity. The product undergoes rigorous analytical testing, including HPLC, GC, and NMR, to confirm identity and assay. A Certificate of Analysis (COA) detailing purity, impurities, and physical parameters is provided with each shipment to support your quality assurance processes.

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). This product is hygroscopic (moisture-sensitive) and light-sensitive; containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent degradation from moisture and to maintain stability. Keep away from heat, sparks, open flames, and incompatible materials such as alcohols, amines, and strong bases.
