Used as an intermediate in the synthesis of fluorescent dyes and optical brighteners due to its strong electron-donating and rigid aromatic structure. Its derivatives are found in agrochemicals, particularly as herbicides and plant growth regulators. Also employed in the development of organic semiconductors and sensors, where the chloro and amino groups allow for further functionalization to tune electronic properties. Shows potential in medicinal chemistry for building heterocyclic compounds with biological activity, including antimicrobial and antitumor agents.
