Used as a key intermediate in the synthesis of high-performance polyimides and polyamides, offering enhanced thermal stability and mechanical strength in aerospace and electronic materials. Employed in the production of specialty dyes and pigments due to its aromatic amine structure, contributing to improved color fastness and light stability. Also utilized in the development of curatives and crosslinking agents for advanced epoxy resins, particularly in coatings and composites requiring superior chemical and heat resistance. Its sterically hindered tert-butyl group helps modify reactivity and solubility in polymer formulations.
