Description

Benzoyl Chloride, 2-Isocyanato- (9Ci) CAS NO 5100-23-2 is a specialized bifunctional reagent that combines the reactivity of an isocyanate group with an acid chloride moiety. This unique structure makes it a valuable building block for synthesizing complex molecules, particularly in the development of advanced polymers and active pharmaceutical ingredients (APIs). It is primarily sought by research and development teams in the pharmaceutical, agrochemical, and specialty polymer industries for creating novel compounds with tailored properties.

Application

• Pharmaceutical Intermediate: A key precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly those requiring urea or carbamate linkages.
• Polymer Chemistry: Used as a monomer or cross-linking agent in the production of polyurethanes, polyureas, and other specialty polymers with enhanced thermal or mechanical properties.
• Agrochemical Synthesis: Serves as a building block for creating novel herbicides, fungicides, and insecticides with specific activity profiles.
• Chemical Research: Employed in organic synthesis for the introduction of both benzoyl and isocyanate functionalities in a single step.
• Material Science: Utilized in surface modification and the development of advanced coatings and adhesives.
• Dye and Pigment Manufacturing: Acts as an intermediate in the synthesis of complex colorants.

Quality Control

Our Benzoyl Chloride, 2-Isocyanato- is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity suitable for demanding synthetic applications. Each lot is analyzed using advanced techniques including HPLC, GC, and NMR spectroscopy. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles 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, well-ventilated area at temperatures between 2°C and 8°C (refrigerated) to maximize stability, due to its moisture-sensitive and reactive nature. Keep away from heat, open flames, and incompatible materials such as strong bases, alcohols, and amines. Allow the container to reach ambient temperature before opening to prevent moisture ingress.
