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, printing, and coating industries. It also serves in the manufacture of specialty chemicals such as agricultural chemicals and pharmaceuticals, where its structure supports the development of active ingredients. Due to the presence of both amine and methoxy groups, it participates in selective chemical reactions useful in fine chemical synthesis. Its ethyl and methoxy substituents influence solubility and reactivity, making it suitable for use in organic transformations requiring moderate electron-donating properties.
