Description

4,4'-Bis(2-Hydroxyhexafluoroisopropyl)Biphenyl is a high-purity, fluorinated biphenyl derivative characterized by its unique hexafluoroisopropanol functional groups. This compound is a critical advanced intermediate valued for its ability to impart exceptional chemical resistance, thermal stability, and low surface energy properties to final materials. It is primarily sought by R&D and production teams in the specialty polymers, advanced coatings, and high-performance material sectors for developing next-generation fluorinated resins and additives.

Application

• Monomer for Fluorinated Polyarylates and Polycarbonates: Serves as a key building block for synthesizing transparent, high-refractive-index, and chemically resistant engineering plastics.
• Intermediate for Specialty Coatings: Used in formulating advanced release coatings, non-stick surfaces, and corrosion-resistant protective layers for demanding industrial environments.
• Additive for Polymer Modification: Imparts hydrophobicity, oleophobicity, and improved weatherability when incorporated into polymer blends.
• Liquid Crystal Polymers (LCPs): Acts as a fluorinated monomer in the production of high-temperature LCPs for electronics and aerospace applications.
• Pharmaceutical & AgroChemical Intermediates: Utilized in the synthesis of complex molecules where fluorination enhances biological activity or metabolic stability.
• Optical Materials: A potential candidate for creating materials with specific optical properties due to its aromatic and fluorinated structure.

Quality Control

Every batch of 4,4'-Bis(2-Hydroxyhexafluoroisopropyl)Biphenyl is manufactured and tested under a strict quality management system. We provide comprehensive Certificates of Analysis (COA) that detail purity, identity, and impurity profiles to ensure consistency and compliance with your specifications. Our quality protocols are designed to meet the rigorous standards required for pharmaceutical intermediates and high-performance polymer 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). Keep away from incompatible materials such as strong bases and fluorinating agents. The container must be kept tightly sealed due to the compound's sensitivity to moisture (hygroscopic nature).
