Used as a key intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the production of active ingredients in herbicides and fungicides. It serves as a building block in organic synthesis due to the presence of reactive bromine atoms and aldehyde group, enabling coupling reactions and functional group transformations. Commonly employed in the preparation of heterocyclic compounds and liquid crystal materials for electronic applications. Also utilized in the development of dyes and fluorescent probes for research and industrial applications.
