Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of anti-inflammatory and analgesic agents. It serves as a building block in organic reactions where the aldehyde group enables the formation of carbon-carbon bonds through condensation or reduction processes. Commonly employed in the preparation of chalcone derivatives, which exhibit biological activity including anticancer and antimicrobial properties. Also utilized in the manufacture of dyes and functional materials due to its aromatic and halogenated structure that enhances electronic properties in conjugated systems.
