Used in the synthesis of pharmaceuticals and fine chemicals, particularly as an intermediate in the production of active pharmaceutical ingredients (APIs) requiring substituted benzaldehyde moieties. Its aldehyde functional group allows for condensation reactions, making it valuable in creating complex organic molecules. Commonly employed in research settings for developing new drug candidates, especially those targeting central nervous system disorders. Also utilized in the fragrance industry due to its aromatic characteristics, contributing to the creation of specialty perfumes and flavoring agents. Serves as a building block in organic synthesis, enabling the formation of carbon-carbon bonds through reactions such as Wittig or aldol condensation.
