Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of dyes and fluorescent compounds. 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. The aldehyde and nitro functional groups allow for further chemical modifications, making it valuable in the preparation of more complex molecules used in research and industrial applications. Also employed in the production of certain photochromic and nonlinear optical materials.
