Used primarily as an intermediate in organic synthesis, especially in the production of dyes and pigments. It serves as a building block for azo dyes due to the presence of both amino and nitro groups, which can be further modified. Also employed in the preparation of pharmaceuticals and agrochemicals where nitro-aromatic scaffolds are required. Its hydroxyl group allows for esterification or ether formation, enabling integration into more complex molecules. Handle with care due to potential toxicity and irritant properties.
