Description

Phenyl Isocyanate CAS NO 103-71-9 is a highly reactive aromatic isocyanate monomer, serving as a critical building block in organic synthesis. Its primary value lies in its ability to introduce the phenylcarbamoyl group, enabling the production of a wide range of ureas, carbamates, and heterocyclic compounds. This chemical is essential for manufacturers and R&D facilities in the agrochemical, pharmaceutical, and polymer industries seeking to develop advanced materials and active ingredients.

Application

• Agrochemical Intermediate: Key precursor in the synthesis of phenylurea herbicides and various pesticide active ingredients.
• Pharmaceutical Synthesis: Used in the production of pharmaceutical intermediates, particularly for compounds containing urea or carbamate functionalities.
• Polymer & Resin Production: Acts as a monomer or cross-linking agent in the manufacture of specialized polyurethanes, coatings, and adhesives.
• Chemical Research & Development: A versatile reagent for introducing the isocyanate group in novel organic compound synthesis.
• Dye & Pigment Manufacturing: Employed in the synthesis of certain azo dyes and colorant intermediates.

Quality Control

Our Phenyl Isocyanate is produced and tested under stringent quality management systems to ensure batch-to-batch consistency and high purity. We provide comprehensive Certificates of Analysis (COA) for each lot, detailing key parameters such as assay, color, and specific impurity profiles. Our quality commitment aligns with industrial and fine chemical standards, and we can support requirements for cGMP manufacturing upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at temperatures between 2°C and 8°C (refrigerated) to minimize volatility and degradation. Due to its highly volatile and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) after opening. Keep away from heat, sparks, open flames, and incompatible materials such as water, alcohols, amines, and strong bases.
