Phenoxazine is widely used as a key intermediate in the synthesis of dyes and pigments, particularly in the production of vibrant and stable colors for textiles and plastics. Its derivatives are also employed in the development of organic light-emitting diodes (OLEDs) due to their efficient electron-transporting properties, enhancing the performance of display technologies. Additionally, phenoxazine-based compounds are explored in medicinal chemistry for their potential as antimicrobial and anticancer agents, leveraging their ability to interact with biological targets. In agrochemicals, phenoxazine derivatives serve as active ingredients in pesticides, offering effective pest control solutions. Its versatility and unique chemical structure make it valuable across various industrial and scientific applications.
