Used as a key intermediate in the synthesis of fluorescent dyes and sensors due to its ability to undergo Schiff base reactions, forming compounds that exhibit strong fluorescence. Widely applied in the development of chemosensors for detecting metal ions such as zinc and aluminum in environmental and biological samples. Also utilized in pharmaceutical synthesis, particularly in the production of certain antimicrobial and anti-inflammatory agents. Its electron-donating dimethylamino group enhances optical properties, making it valuable in nonlinear optical materials research. Additionally, it serves as a derivatizing agent in analytical chemistry for the detection of carbonyl compounds and amines.
