Used as a key intermediate in the synthesis of dyes and pigments, particularly in the production of triarylmethane dyes which are widely applied in textiles, inks, and biological staining. Also serves as a building block in the preparation of pharmaceuticals and agrochemicals due to its amine functionality and aromatic structure. Its derivative formation is valuable in developing photochromic and fluorogenic compounds for sensors and imaging agents. Additionally, it finds use in the development of corrosion inhibitors and epoxy curing agents in industrial coatings.
