Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of antihypertensive and antiviral agents. It serves as a building block in organic reactions, especially in cross-coupling processes like Suzuki and Heck reactions, due to the presence of the bromine atom. Its aldehyde and methoxy functional groups allow for further derivatization, making it valuable in the preparation of agrochemicals, dyes, and fine chemicals. Commonly employed in research laboratories for constructing complex aromatic structures.
