Used as an intermediate in the synthesis of pharmaceuticals, particularly in the production of active pharmaceutical ingredients (APIs) where chlorinated benzaldehyde derivatives are required. Its functional groups allow for selective reactions in multi-step organic syntheses. Commonly employed in the development of cardiovascular drugs and anti-inflammatory agents due to its ability to form complex aromatic structures. Also utilized in the preparation of agrochemicals and fine chemicals where controlled substitution patterns on aromatic rings are essential. Its stability under various reaction conditions makes it suitable for use in cross-coupling reactions and nucleophilic substitutions.
