Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of active pharmaceutical ingredients (APIs) that require substituted benzaldehyde derivatives. Its structure allows for further functionalization, making it valuable in creating complex organic molecules. Commonly employed in the development of antihypertensive and anti-inflammatory drugs due to its ability to participate in condensation and coupling reactions. Also utilized in agrochemical synthesis for the preparation of certain herbicides and fungicides. Its electron-withdrawing chloro groups and methoxy functionality enhance reactivity in nucleophilic addition and substitution processes, enabling efficient route design in fine chemical manufacturing.
