Description

4-(n-Butoxycarbonyl)Phenyl Isocyanate is a specialized aromatic isocyanate derivative, a key building block in advanced organic synthesis. Its primary value lies in its highly reactive isocyanate group, which readily forms urethane linkages, making it indispensable for creating custom polymers and fine chemicals. This compound is particularly sought after by R&D chemists and process engineers in the pharmaceutical, agrochemical, and advanced materials sectors for synthesizing novel compounds with tailored properties.

Application

• Key intermediate in the synthesis of pharmaceutical active ingredients (APIs), particularly for candidates targeting central nervous system disorders.
• Building block for novel agrochemicals, including herbicides and fungicides, where the phenyl isocyanate moiety is incorporated for enhanced bioactivity.
• Monomer for the production of specialized polyurethanes and polyurea coatings with unique optical or mechanical properties.
• Reagent for the derivatization of amines and alcohols in analytical chemistry and proteomics research.
• Starting material for liquid crystal polymers (LCPs) and other high-performance engineering plastics.
• Cross-linking agent in the formulation of advanced adhesives and sealants requiring chemical and thermal resistance.

Quality Control

Our 4-(n-Butoxycarbonyl)Phenyl Isocyanate is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation by FT-IR and NMR spectroscopy, to ensure it meets the high standards required for research and industrial synthesis. Certificates of Analysis (COA) with detailed chromatographic data are provided for every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at 2-8°C under an inert atmosphere (e.g., nitrogen or argon) due to its moisture-sensitive and light-sensitive nature. Keep away from heat, open flames, and sources of ignition. Separate from alcohols, amines, and other nucleophiles.
