Primarily used in the dye industry, p-Anisidine serves as an intermediate in the synthesis of various azo dyes, which are widely applied in textiles, leather, and paper products. It also plays a role in the production of pharmaceuticals, particularly in the synthesis of specific drugs and organic compounds. In analytical chemistry, it is employed as a reagent for detecting and quantifying aldehydes, and to a lesser extent, certain sugars. Its applications extend to agrochemicals for the development of pesticides and herbicides, and to cosmetics in the production of antioxidants and UV protectors. However, it should be handled with caution as it may be toxic to humans and the environment.
