Used as an intermediate in the synthesis of dyes and pigments, particularly in the production of azo dyes which are widely applied in the textile industry for coloring fabrics. It also serves in the preparation of certain photographic chemicals and fluorescent whiteners. In research, it is employed as a building block for more complex organic molecules, especially in the development of compounds with biological activity. Additionally, it finds use in the formulation of some agrochemicals and in the synthesis of specialty polymers.
