Description

4-(4-Cyanophenoxy)Benzoic Acid is a high-purity organic intermediate featuring a biphenyl ether core functionalized with a cyano and a carboxylic acid group. This compound matters for its role as a versatile building block in the synthesis of advanced materials and active pharmaceutical ingredients (APIs), offering precise molecular architecture for downstream chemical processes. It is primarily needed by manufacturers in the pharmaceutical, liquid crystal, and specialty polymer industries seeking reliable, high-quality raw materials for research and production.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of novel drug candidates and active pharmaceutical ingredients (APIs), particularly those with liquid crystalline properties or designed for targeted delivery.
• Liquid Crystal Materials: Serves as a core building block for high-performance liquid crystal monomers and mixtures used in display technologies (LCDs).
• Polymer & Resin Synthesis: Used in the production of specialty polymers, polyesters, and epoxy resins, where its aromatic structure and functional groups enhance thermal and mechanical properties.
• Agrochemical Intermediates: Employed in the research and development of advanced herbicides and pesticides.
• Organic Synthesis & Research: A valuable reagent in academic and industrial R&D for constructing complex organic molecules, dyes, and pigments.
• Cross-coupling Reactions: Useful in palladium-catalyzed reactions like Suzuki or Buchwald-Hartwig couplings due to its halogenated derivative potential.

Quality Control

Our 4-(4-Cyanophenoxy)Benzoic Acid is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via FT-IR and NMR, to ensure it meets exacting specifications for high-end applications. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to guarantee traceability and compliance with your quality protocols.

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 after opening to prevent degradation from atmospheric moisture.
