Used as an intermediate in the synthesis of flame-retardant polymers due to its ability to introduce hydroxyl groups into polymer chains. It is also employed in the production of specialty resins and coatings, where its rigid phenyl group enhances thermal stability and mechanical strength. Additionally, it serves as a building block in the formulation of crosslinking agents for adhesives and elastomers, improving durability and resistance to moisture. Its bifunctional hydroxyl structure makes it suitable for polyurethane and epoxy resin modifications.
