Used as an intermediate in the synthesis of dyes, pharmaceuticals, and agrochemicals. It plays a key role in the preparation of anthranilic acid derivatives, which are important in the development of nonsteroidal anti-inflammatory drugs (NSAIDs). Also utilized in the production of fluorescent dyes and optical brighteners due to its ability to undergo specific reduction and cyclization reactions. Its derivatives show potential in coordination chemistry as ligands for metal ions in catalytic applications.
