Description

3 3 -Diphenylpropyl Isocyanate 97 CAS NO 41347-11-9 is a versatile aromatic isocyanate monomer, essential for introducing the diphenylpropyl moiety into polymer backbones. Its primary value lies in its role as a key building block for synthesizing specialized polyurethanes, polyureas, and other advanced materials with tailored properties. This compound is particularly needed by R&D chemists and manufacturers in the pharmaceutical intermediates, agrochemical, and high-performance polymer industries seeking to develop products with specific mechanical and chemical resistance characteristics.

Application

• Pharmaceutical Intermediate: Serves as a crucial precursor in the synthesis of active pharmaceutical ingredients (APIs) and drug candidates, particularly those requiring a rigid, aromatic backbone.
• Agrochemical Synthesis: Used in the production of specialized herbicides, fungicides, and pesticides where its structural motif imparts desired biological activity and stability.
• Polymer & Resin Modification: Acts as a core monomer for manufacturing high-performance polyurethane elastomers, coatings, adhesives, and sealants with enhanced thermal and chemical resistance.
• Crosslinking Agent: Functions as an effective crosslinker in polymer systems to improve hardness, durability, and solvent resistance of the final cured material.
• Chemical Research & Development: A valuable reagent for organic synthesis, enabling the introduction of isocyanate and aromatic groups into complex molecules in academic and industrial labs.
• Specialty Material Production: Employed in creating advanced materials such as liquid crystal polymers, photoresists, and other functional materials requiring precise molecular architecture.

Quality Control

Our 3,3-Diphenylpropyl Isocyanate is produced under stringent quality management systems. Every batch undergoes rigorous analytical testing, including HPLC for purity verification and identity confirmation via spectroscopic methods, to ensure it meets the specified 97% minimum purity and consistent performance. Certificates of Analysis (COA) documenting all critical parameters are available upon request to support your quality assurance and regulatory needs.

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 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.
