Used in the synthesis of fluorescent dyes and optical brighteners due to its conjugated aldehyde group that facilitates attachment to aromatic systems. Serves as an intermediate in pharmaceuticals, particularly in the development of compounds with antimicrobial and antitumor activities. Employed in agrochemicals for the production of plant growth regulators and pesticides. Its structure supports coordination with metal ions, making it useful in the design of sensors and catalysts. Also applied in material science for creating organic semiconductors and luminescent materials.
