Description

4-Isocyanatobenzophenone 97 is a high-purity aromatic isocyanate derivative, serving as a critical building block in advanced organic synthesis. Its primary value lies in its dual functional groups—the reactive isocyanate and the benzophenone moiety—which enable its use in creating specialized polymers and fine chemicals. This compound is essential for R&D and production chemists in the pharmaceutical, agrochemical, and advanced materials sectors seeking to develop novel photoactive compounds, cross-linking agents, or high-performance polymer precursors.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly those requiring benzophenone-based photophores or urethane linkages.
• Agrochemical Synthesis: Used in the development of novel herbicides, fungicides, and pesticides where the isocyanate group facilitates the formation of urea or carbamate derivatives.
• Polymer & Resin Modification: Acts as a cross-linking agent or chain extender in polyurethane, polyurea, and other specialty polymer systems to enhance thermal stability and mechanical properties.
• Photoinitiator & UV-Curable Systems: The benzophenone core makes it valuable in formulating photoinitiators for inks, coatings, and adhesives that cure under UV light.
• Advanced Material Research: Employed in the development of liquid crystals, organic semiconductors, and other functional materials requiring precise molecular architecture.
• Chemical Derivatization Agent: Useful for introducing the isocyanate functional group onto other molecules for further conjugation or analytical purposes.

Quality Control

Our 4-Isocyanatobenzophenone 97 is manufactured under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC for purity verification and identity confirmation by FT-IR and NMR spectroscopy, to ensure it meets the specified 97% minimum assay. A comprehensive Certificate of Analysis (COA) detailing purity, impurities, and physical parameters is provided with every shipment to guarantee traceability and compliance with your internal quality standards.

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 hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation from atmospheric moisture. Keep away from heat, sparks, and open flame.
