Description

4-Chlorobenzyl Isocyanate 97 CAS NO 30280-44-5 is a versatile aromatic isocyanate derivative, serving as a critical building block in advanced organic synthesis. Its primary value lies in its highly reactive isocyanate group, which readily forms stable urethane and urea linkages, enabling the creation of complex molecular architectures. This compound is essential for research and production in the pharmaceutical and agrochemical industries, where it is used to synthesize active ingredients, intermediates, and functional polymers.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of active pharmaceutical ingredients (APIs), particularly in the development of urea and carbamate-based drugs.
• Agrochemical Synthesis: Used in the production of herbicides, fungicides, and pesticides, where it acts as a precursor for bioactive molecules.
• Polymer Chemistry: Serves as a monomer or cross-linking agent in the manufacture of polyurethanes, polyureas, and specialty coatings with tailored properties.
• Chemical Research: A valuable reagent in organic synthesis for introducing the 4-chlorobenzyl carbamoyl moiety into target molecules.
• Material Science: Employed in the development of advanced materials, including adhesives, sealants, and elastomers requiring specific chemical resistance.

Quality Control

Our 4-Chlorobenzyl Isocyanate is manufactured under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including assay by HPLC and impurity profiling, to ensure it meets the specified 97% purity grade and consistent performance. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming compliance with our rigorous internal specifications.

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) to prevent degradation from moisture.
