Description

Perylene-3,4,9,10-Tetracarboxylic Acid is a high-purity, polycyclic aromatic organic compound that serves as a critical intermediate in the synthesis of advanced pigments and functional materials. Its rigid, planar perylene core and four carboxylic acid groups make it an essential building block for creating vivid, stable colors and high-performance electronic components. This product is primarily required by manufacturers in the pigments and dyes, organic electronics, and specialty chemical synthesis industries.

Application

• Perylene Pigment Synthesis: As a key precursor for manufacturing high-performance perylene red and perylene maroon pigments, known for exceptional lightfastness and weather resistance.
• Organic Semiconductor Materials: Used in the synthesis of n-type semiconductors, electron-transport materials, and active layers for organic photovoltaics (OPVs) and organic light-emitting diodes (OLEDs).
• Liquid Crystal Dyes and Additives: Imparts color and can modify the electro-optical properties of liquid crystal displays (LCDs).
• Fluorescent Dyes and Sensors: Basis for creating highly fluorescent derivatives used in biological staining, chemical sensors, and laser dyes.
• Advanced Polymer Composites: Acts as a functional monomer or additive to enhance the thermal stability and electrical properties of engineering plastics.
• Research & Development: Serves as a fundamental compound in academic and industrial R&D for exploring new organic electronic materials and supramolecular chemistry.
