Used primarily as a cross-linking agent in polymer chemistry, this compound enhances the thermal and mechanical stability of resins and plastics. It is employed in the synthesis of rigid polyurethanes and phenolic resins, where it improves flame resistance and structural integrity. Its reactivity with nucleophiles makes it useful in the preparation of specialty intermediates for agrochemicals and pharmaceuticals. Additionally, it serves as a building block in the creation of dendritic and hyperbranched polymers due to its trifunctional structure. Handling requires caution due to its lachrymatory and moisture-sensitive properties.
