Used primarily as a coupling component in the synthesis of azo dyes and pigments, this compound plays a key role in the production of colorants for textiles, plastics, and printing inks. Its active methylene structure facilitates coupling reactions with diazonium salts, making it valuable in creating yellow and orange shades with good light and heat stability. It is also employed in the manufacture of certain agricultural chemicals and pharmaceuticals where chlorinated aniline derivatives are required. Due to its reactivity, it is handled under controlled conditions in industrial settings.
