Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of active ingredients requiring substituted benzaldehyde derivatives. Its functional groups enable coupling reactions and ring modifications, making it valuable in creating complex organic molecules. Commonly employed in the production of dyes, fragrances, and specialty polymers due to its reactivity and structural properties. Also utilized in research laboratories for building blocks in organic synthesis, especially in cross-coupling and electrophilic substitution reactions.
