Description

4-Bromobenzyl Isocyanate 98 is a versatile aromatic isocyanate building block, primarily valued for its role as a key intermediate in the synthesis of more complex chemical entities. Its high purity grade of 98% makes it a reliable reagent for demanding research and development applications where consistency is critical. This compound is essential for scientists and process chemists in the pharmaceutical, agrochemical, and specialty chemical industries, particularly for constructing ureas, carbamates, and other functionalized molecules.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of active pharmaceutical ingredients (APIs) and drug candidates, especially those containing urea or carbamate functional groups.
• Agrochemical Synthesis: Used in the research and production of advanced herbicides, fungicides, and pesticides, where the bromobenzyl moiety can impart specific biological activity.
• Polymer & Material Science: Serves as a monomer or cross-linking agent in the development of specialty polyurethanes, coatings, and adhesives with tailored properties.
• Chemical Research & Development: A crucial reagent in medicinal chemistry and organic synthesis for introducing the isocyanate functional group into molecular scaffolds.
• Ligand & Catalyst Development: Utilized in the preparation of specialized ligands for metal-organic frameworks (MOFs) or catalysts.

Quality Control

Our 4-Bromobenzyl Isocyanate 98 is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity. Each lot is analyzed to confirm identity, purity, and the absence of critical impurities. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment 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 an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
