Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and agrochemicals. It serves as a building block for introducing bromoethyl and naphthyl functional groups into more complex molecules. Commonly employed in the synthesis of ketones, heterocyclic compounds, and bioactive derivatives through nucleophilic substitution or cyclization reactions. Its reactivity makes it valuable in medicinal chemistry for developing potential drug candidates with central nervous system activity or anti-inflammatory properties. Also utilized in research settings for labeling and derivatization in analytical chemistry.
