Used primarily as a curing agent for high-performance epoxy resins in aerospace and electronic applications due to its ability to form thermally stable and mechanically strong networks. It is also employed in the production of polyimides and other specialty polymers where excellent heat resistance and dimensional stability are required. In the medical field, it serves as an active ingredient in certain dermatological treatments, particularly for conditions like dermatitis herpetiformis and leprosy, owing to its anti-inflammatory properties. Additionally, it finds use in the synthesis of dyes and as a crosslinking agent in some elastomers.
