Used primarily as an intermediate in the synthesis of dyes, particularly for hair coloring products. It plays a key role in producing vibrant and long-lasting shades due to its ability to form stable colorants when combined with other dye components. Additionally, it is utilized in the manufacturing of specialty chemicals for textiles, including dyes for cellulose fibers such as cotton and linen, where it contributes to the creation of colorfast and durable fabric dyes through chemical bonding with fibers. Its sulfate form ensures better solubility and handling during industrial processes, and it may also support research for developing new high-efficiency dyes.
