Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of active ingredients for agrochemicals and medicinal compounds. Its structure allows for selective functionalization, making it valuable in creating complex organic molecules. Commonly employed in cross-coupling reactions, it helps build carbon-carbon bonds in the production of fluorinated compounds with enhanced metabolic stability and bioavailability. Also utilized in the manufacture of herbicides and fungicides due to the favorable reactivity of the bromine and aldehyde groups.
