Used as a building block in polymer synthesis, particularly in the production of specialty polyesters and alkyd resins. Its trifunctional structure enables cross-linking, enhancing the thermal and mechanical properties of the resulting materials. Also employed in the preparation of UV-curable coatings and as a precursor for flame-retardant additives. Additionally, it finds use in organic synthesis for creating dendrimers and other branched macromolecules due to its symmetrical structure and multiple hydroxyl groups.
