Used in organic synthesis as a key intermediate for the production of various pharmaceuticals and agrochemicals. Its reactive aldehyde group allows for the creation of complex molecules through condensation, oxidation, or reduction reactions. Commonly employed in the development of heterocyclic compounds, which are essential in drug discovery and crop protection. Also serves as a building block in the synthesis of dyes and pigments due to its ability to form stable conjugated systems. In research, it is utilized to study chemical reactivity and to develop novel organic frameworks.
