Used primarily as an intermediate in the synthesis of dyes and pigments, especially in the production of azo dyes where its functional groups allow for coupling reactions. Its nitro and amino groups make it valuable in the development of photochromic compounds, which change color under UV light, useful in specialty optical materials and sensors. Also employed in the preparation of certain pharmaceuticals and agrochemicals due to its reactivity and ability to undergo substitution and reduction reactions. Its bromine moiety facilitates further derivatization through cross-coupling reactions in organic synthesis.
