Perylene-3,4,9,10-tetracarboxylic acid is widely used in the production of high-performance pigments due to its ability to form vivid and stable colors. These pigments are employed in automotive coatings, plastics, and inks, offering excellent lightfastness and heat resistance. Additionally, it serves as a key intermediate in the synthesis of perylene diimide dyes, which are utilized in organic electronics, including organic light-emitting diodes (OLEDs) and photovoltaic cells, due to their electron-transporting properties. Its derivatives are also explored in the field of supramolecular chemistry for creating functional materials with specific optical and electronic characteristics. Furthermore, it is used in analytical chemistry as a fluorescent probe for detecting and studying various biological and chemical processes.
