Primarily used in the synthesis of polymers, particularly in the production of thermosetting resins. These resins are essential in creating durable coatings, adhesives, and composite materials, offering high thermal stability and chemical resistance. Additionally, it serves as a key intermediate in the development of flame retardants, enhancing the safety of textiles, plastics, and construction materials. Its role in crosslinking reactions also makes it valuable in the formulation of advanced materials for the electronics and automotive industries.
