Used as an intermediate in organic synthesis, particularly in the production of pharmaceuticals and agrochemicals. It serves as a key building block for creating compounds with potential biological activity. In pharmaceutical research, it is employed to develop molecules for drug discovery, especially in the synthesis of anti-inflammatory and antimicrobial agents. Additionally, it finds application in the synthesis of specialty chemicals and dyes, where its aldehyde and bromine functional groups allow for versatile chemical transformations. Its role in cross-coupling reactions is also significant for constructing complex organic frameworks.
