This chemical is primarily used in organic synthesis as a diazonium salt, which is highly reactive and serves as a key intermediate in various chemical reactions. It is commonly employed in the preparation of azo dyes, where it acts as a coupling agent to produce vibrant and stable colorants for textiles, inks, and pigments. Additionally, it is utilized in the synthesis of aryl compounds through Sandmeyer reactions, enabling the replacement of the diazonium group with halogens, cyano groups, or other substituents in nitroaromatic systems. Its role in photoaffinity labeling is also notable, as it helps in studying molecular interactions and binding sites in biochemical research. Due to its reactivity, it is often handled with care in controlled environments.
