Used as a curing agent and crosslinking agent in epoxy resin systems, providing high thermal stability and mechanical strength to the final product. Commonly applied in aerospace, electronics, and composite materials where durability under high temperature and stress is required.

Also utilized in the synthesis of polyimides and other high-performance polymers for coatings, adhesives, and electrical insulation. Its structure allows for improved resistance to oxidation and chemical degradation, making it suitable for harsh environments.

Additionally, it serves as an intermediate in the production of azo dyes, pigments, and other specialty chemicals, particularly in the paint and ink industries where its multi-amine structure enhances lightfastness and water resistance.
