Description

Benzoyl Chloride, 4-Chloro-3-Cyano- (9Ci) CAS NO 181283-43-2 is a specialized aromatic acid chloride derivative, serving as a critical building block in advanced organic synthesis. Its value lies in its dual functional groups—the reactive benzoyl chloride moiety and the chloro-cyano substitution pattern—which enable precise molecular construction. This compound is essential for researchers and manufacturers in the pharmaceutical and agrochemical industries who require high-purity intermediates for developing active ingredients and functional materials.

Application

• Pharmaceutical Intermediate: A key precursor in the synthesis of complex drug molecules, particularly those requiring a substituted benzoyl scaffold.
• Agrochemical Synthesis: Used in the production of advanced herbicides, fungicides, and insecticides where the chloro-cyano group imparts specific biological activity.
• Dye and Pigment Manufacturing: Serves as an intermediate for creating specialized colorants and functional dyes.
• Polymer Chemistry: Acts as a monomer or cross-linking agent in the synthesis of high-performance polymers and resins.
• Liquid Crystal & OLED Materials: Employed in the research and development of electronic display materials due to its molecular structure.
• Chemical Research & Development: A valuable reagent for academic and industrial R&D labs exploring new synthetic pathways and novel compounds.
