Used as a building block in the synthesis of liquid crystals and organic semiconductors due to its rigid aromatic core and reactive hydroxyl groups. It serves in the preparation of specialty polymers and polyesters, where it contributes thermal stability and structural rigidity. Also employed in the development of crosslinking agents for coatings and resins, enhancing durability and chemical resistance. Its bifunctional nature makes it suitable for use in pharmaceutical intermediates and in the design of dendrimers or supramolecular structures.
