Used primarily as an intermediate in the synthesis of dyes and pigments, especially triphenylmethane dyes, which are valued for their intense color and use in textiles, inks, and biological staining. Also serves as a building block in the production of certain pharmaceuticals and agrochemicals due to its chlorinated aromatic structure, which can enhance bioactivity. Its amine functionality allows for easy modification in multi-step organic syntheses, making it useful in research and development of specialty chemicals.
