Description

4,4''-Dihydroxydiphenyl Ether 99%(Hplc) is a high-purity diaryl ether derivative, also known as 4,4'-Oxydiphenol, characterized by its two phenolic hydroxyl groups. This compound is a crucial high-purity building block and intermediate in advanced organic synthesis, valued for its symmetrical aromatic structure. It is primarily utilized by manufacturers in the pharmaceutical, polymer, and specialty chemical industries for developing active pharmaceutical ingredients (APIs), high-performance polymers, and liquid crystal materials.

Application

• Pharmaceutical Intermediate: A key synthon for the production of various active pharmaceutical ingredients (APIs), particularly those with ether-linked aromatic systems.
• Polymer Chemistry: Serves as a monomer or chain extender in the synthesis of high-performance engineering plastics, polyesters, and polycarbonates, imparting thermal and chemical resistance.
• Liquid Crystal Materials: Used as a core structure in the manufacture of monomers for liquid crystal displays (LCDs) due to its rigid, linear geometry.
• Antioxidant Synthesis: Acts as a precursor in the production of specialized phenolic antioxidants for plastics and rubber stabilization.
• Cross-linking Agent: Employed in epoxy resin systems and other thermosetting polymers to enhance network density and material properties.
• Research & Development: A valuable reagent in academic and industrial R&D for exploring new organic reactions and material science applications.

Quality Control

Our 4,4''-Dihydroxydiphenyl Ether is produced under a strict quality management system. Every batch is analyzed to confirm it meets the high-purity specification of 99% (by HPLC). Certificates of Analysis (COA) documenting identity, purity, and related substances are available upon request to ensure traceability and compliance for your critical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture. For long-term storage, consider using an inert atmosphere to minimize potential oxidation.
