Used as a key intermediate in the synthesis of pharmaceuticals and agrochemicals due to its reactive bromomethyl and aldehyde functional groups. The compound is particularly valuable in the preparation of heterocyclic compounds, such as benzoxepines and indole derivatives, which are common structural motifs in bioactive molecules. It also serves in the development of fluorescent probes and dyes, leveraging the aldehyde group for conjugation with other aromatic systems. Its versatility in organic transformations, including nucleophilic substitution and condensation reactions, makes it a preferred building block in medicinal chemistry and materials science.
