Used as an intermediate in the synthesis of heterocyclic compounds, particularly in the preparation of benzimidazoles and other nitrogen-containing rings which have applications in pharmaceuticals and agrochemicals. It serves as a building block in the development of dyes and fluorescent probes due to its ability to undergo condensation reactions with carbonyl compounds. Also employed in the fabrication of sensors for metal ion detection, leveraging its amine and aldehyde functional groups for selective binding and signal generation. Its reactivity makes it valuable in organic synthesis for constructing complex molecules in research and industrial settings.
