Used as an intermediate in the synthesis of pharmaceuticals and fine chemicals, particularly in the development of active pharmaceutical ingredients (APIs) where substituted benzaldehydes serve as building blocks. Its functional groups allow for selective reactions, making it valuable in creating complex organic molecules. Commonly employed in the preparation of analgesics and anti-inflammatory agents. Also utilized in the fragrance and flavor industry due to its aromatic aldehyde structure, contributing to the creation of specialty scent compounds.
