Used in organic synthesis as an intermediate for pharmaceuticals and agrochemicals. Serves as a building block in the preparation of ligands for catalytic reactions, particularly in transition metal catalysis. Its aldehyde functionality allows for condensation reactions, enabling the formation of Schiff bases and other nitrogen-containing heterocycles. Also applied in the development of fluorescent probes and sensors due to its ability to coordinate with metal ions and exhibit photophysical properties. Investigated for use in materials science, particularly in designing organic semiconductors and coordination polymers.
