Description

1,1':4',1'':4'',1'''-Quaterphenyl-4,4'''-Disulfonic Acid Dipotassium Salt is a high-purity, water-soluble derivative of quaterphenyl, functionalized with sulfonic acid groups. This compound is valued for its role as a key intermediate in the synthesis of advanced materials and specialty chemicals, offering excellent solubility and ionic character. It is primarily sought by manufacturers in the electronic materials, liquid crystal displays (LCDs), and organic light-emitting diode (OLED) sectors for its utility in creating charge-transport layers and other functional components.

Application

• Electronic Materials: As a crucial intermediate or dopant in the manufacture of charge transport materials for organic electronics.
• Liquid Crystal Displays (LCDs): Used in the synthesis of alignment layers or other functional components within display panels.
• Organic Light-Emitting Diodes (OLEDs): Serves as a building block for emissive or conductive layers in display and lighting technologies.
• Specialty Dyes and Pigments: Acts as a sulfonated precursor for creating water-soluble, high-performance colorants.
• Polymer Modification: Incorporated to impart ionic functionality or enhance solubility in advanced polymer systems.
• Research & Development: Utilized in academic and industrial R&D for exploring new organic semiconductors and electro-optic materials.
• Pharmaceutical Intermediates: Potential use in the synthesis of certain drug molecules requiring a rigid, polyaromatic sulfonate core.

Quality Control

Our 1,1':4',1'':4'',1'''-Quaterphenyl-4,4'''-Disulfonic Acid Dipotassium Salt is produced under a stringent quality management system. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets exacting specifications for advanced material synthesis. Certificates of Analysis (COA) documenting all critical parameters are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect product performance.
