Description

4-Cyanophenol is a versatile organic intermediate featuring both a phenolic hydroxyl group and a nitrile functionality, making it a valuable building block for advanced chemical synthesis. This compound is essential for the production of pharmaceuticals, agrochemicals, and high-performance polymers, where precise molecular architecture is critical. Industries such as fine chemical manufacturing, pharmaceutical R&D, and material science rely on high-purity 4-Cyanophenol CAS NO 767-00-0 for its reactivity and consistency in creating complex target molecules.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly for compounds with analgesic, anti-inflammatory, or central nervous system activity.
• Agrochemical Synthesis: Used in the manufacture of herbicides, fungicides, and plant growth regulators, leveraging the phenol and nitrile groups for structural diversity.
• Polymer & Material Science: Serves as a monomer or cross-linking agent for engineering plastics, epoxy resins, and liquid crystal polymers (LCPs).
• Dye & Pigment Manufacturing: Acts as an intermediate for producing azo dyes and other complex colorants.
• Organic Synthesis Building Block: Utilized in coupling reactions (e.g., Suzuki, Heck) and for introducing the cyanophenol moiety into more complex heterocyclic and aromatic systems.
• Chemical Research & Development: Employed in academic and industrial labs for method development and exploring new synthetic pathways.
