Used primarily as an intermediate in the synthesis of azo dyes and pigments, this compound plays a key role in the production of colorants for textiles, inks, and coatings. It is also employed in the preparation of certain pharmaceuticals and agrochemicals due to its reactivity in forming nitrogen-containing heterocycles. Additionally, it serves as a derivatizing agent in analytical chemistry for the detection and quantification of carbonyl compounds such as aldehydes and ketones.
