Used primarily in the synthesis of high-performance polymers, particularly polybenzoxazoles (PBOs), which are known for their exceptional thermal stability and mechanical strength. These polymers are utilized in aerospace, automotive, and electronics industries for applications requiring materials that can withstand extreme temperatures and stress. Additionally, it serves as a key intermediate in the production of dyes and pigments, contributing to the development of colorants with enhanced durability and resistance to fading. Its role in organic synthesis also extends to the creation of advanced materials for coatings and adhesives, offering improved performance in harsh environments.
