Used as an intermediate in the synthesis of dyes and pigments due to its reactive aldehyde and carboxylic acid functional groups. Its nitro group enhances electron-withdrawing properties, making it valuable in the preparation of azo compounds and other aromatic derivatives used in textile and printing industries. Also employed in the development of pharmaceuticals where nitroaromatic scaffolds are required for bioactive molecule design. Additionally, it serves as a building block in organic synthesis for constructing more complex molecules in research laboratories.
