Description

4-Cyano Phenol is a versatile organic intermediate featuring both a phenolic hydroxyl group and a cyano substituent on the aromatic ring. This bifunctional structure makes it a valuable building block for synthesizing more complex molecules in advanced chemical manufacturing. It is particularly essential for industries involved in pharmaceuticals, agrochemicals, and polymer science. Our supply of 4-Cyano Phenol CAS NO 769-79-9 ensures high purity and consistent quality for critical R&D and production processes.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of various active pharmaceutical ingredients (APIs), including potential enzyme inhibitors and receptor modulators.
• Agrochemical Synthesis: Used in the production of herbicides, fungicides, and insecticides, where the cyano-phenol core contributes to biological activity.
• Polymer & Material Science: Serves as a monomer or modifier in the production of high-performance polymers, resins, and liquid crystal materials.
• Dye & Pigment Manufacturing: Acts as an intermediate for creating specialized dyes and organic pigments.
• Cross-Coupling Reactions: A useful substrate in palladium-catalyzed reactions like Suzuki and Heck couplings for constructing complex biaryl structures.
• Research & Development: Employed in academic and industrial labs for method development and exploring new synthetic pathways.
