Used primarily in the production of high-performance polymers and composites, this chemical serves as a key monomer in the synthesis of cyanate ester resins. These resins are highly valued in aerospace and electronics industries due to their exceptional thermal stability, low dielectric properties, and resistance to moisture. It is also employed in the manufacturing of adhesives and coatings that require durability under extreme conditions. Additionally, its application extends to advanced materials used in circuit boards and radomes, where performance under high temperatures and harsh environments is critical.
