Used primarily as an intermediate in the synthesis of dyes and pigments, especially in the production of azo dyes which are valued for their vibrant colors and stability. It also serves in the preparation of certain pharmaceuticals and agrochemicals where nitroaniline derivatives are key building blocks. Due to the presence of both iodo and nitro functional groups, it is useful in coupling reactions, particularly in palladium-catalyzed cross-coupling processes common in organic synthesis and drug development. Additionally, it finds use in research laboratories for the development of new chemical entities requiring selective functionalization on aromatic rings.
