Used primarily as an intermediate in the synthesis of agrochemicals and pharmaceuticals. It serves as a building block for the preparation of certain herbicides and plant growth regulators due to the reactivity of the hydrazine group and the electron-withdrawing effect of the chlorine substituents. Also employed in the development of dyes and pigments, where it contributes to color stability and intensity. Its structure allows for diazotization and coupling reactions, making it valuable in the production of azo compounds for specialized industrial applications.
