Used as a key intermediate in the synthesis of high-performance polymers, particularly in the production of specialty polyamides and polyimides. Its aromatic structure with amino and hydroxyl functional groups allows for strong molecular cross-linking, enhancing thermal stability and mechanical strength in the resulting materials. Commonly applied in advanced composite materials for aerospace and electronics, where resistance to heat and chemicals is critical. Also utilized in the development of curable resins and coatings requiring durable, rigid structures. Additionally, serves as a building block in pharmaceutical synthesis due to its bifunctional reactivity and structural versatility.
