Description

2-Bromoethyl Isocyanate is a versatile bifunctional building block containing both a reactive isocyanate group and a bromoalkyl moiety. This compound is critical for the synthesis of complex molecules, particularly in pharmaceutical and agrochemical research, where it serves as a key intermediate for introducing functionalized ethyl linkers. It is primarily utilized by R&D chemists and process development scientists in the fine chemical, pharmaceutical, and crop protection industries to create novel active ingredients and advanced materials.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of urea and carbamate derivatives with potential biological activity.
• Agrochemical Synthesis: Used in the production of herbicides, fungicides, and insecticides by incorporating the bromoethyl isocyanate moiety into active molecules.
• Polymer Modification: Serves as a functional monomer or cross-linking agent for producing specialty polyurethanes and polymers with tailored properties.
• Bioconjugation Reagent: Facilitates the labeling and modification of biomolecules (e.g., peptides, proteins) for diagnostic and research applications.
• Chemical Research: A valuable reagent in organic synthesis for constructing heterocycles and other complex molecular architectures.
• Material Science: Used in surface coating formulations and the development of advanced functional materials.

Quality Control

Our 2-Bromoethyl Isocyanate is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity suitable for research and industrial synthesis. Each lot is analyzed using advanced techniques including GC, HPLC, and NMR to verify identity and purity. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment to support your quality assurance and regulatory documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at temperatures between 2°C and 8°C (refrigerated) or as specified on the label. Due to its hygroscopic and moisture-sensitive nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening. Keep away from strong bases and incompatible materials.
