Widely used as a key intermediate in the synthesis of fluorescent dyes and optical brighteners, particularly in textile and paper industries. Its structure supports strong light absorption and emission, making it valuable in developing sensors and luminescent materials. Also employed in the preparation of organic semiconductors and electroluminescent devices. Shows potential in medicinal chemistry as a scaffold for developing bioactive molecules, including anti-inflammatory and anticancer agents, due to its ability to interact with biological targets through hydrogen bonding and π-π stacking.
