Used as a key intermediate in the synthesis of fluorescent dyes and optical brighteners due to its aldehyde and amino functional groups, which allow for easy conjugation and extension of π-electron systems. Its structure supports strong absorption and emission properties, making it valuable in developing sensors for metal ions, especially zinc and copper in biological and environmental samples. Also employed in pharmaceutical research for building heterocyclic compounds with potential bioactivity, including kinase inhibitors and anti-inflammatory agents. Its dimethylamino group enhances solubility and electron-donating capacity, improving performance in dye-sensitized solar cells and nonlinear optical materials.
