This chemical is primarily used in the production of diazo dyes, which are essential in the textile industry for coloring fabrics. It acts as a key intermediate in the synthesis of azo compounds, which are known for their bright and stable colors. Additionally, it finds application in the manufacturing of light-sensitive materials, particularly in the production of diazo-type photocopying papers. Its role in these processes is crucial for achieving high-quality prints and durable fabric dyes.
