Used as a crosslinking agent in polymer chemistry, particularly in the development of advanced epoxy resins. Its strained epoxide ring enables efficient ring-opening reactions with nucleophiles like amines and alcohols, facilitating the formation of highly crosslinked networks. These networks exhibit improved thermal stability, mechanical strength, and chemical resistance, making them suitable for high-performance coatings, electronic encapsulants, and composite materials. Also explored in the synthesis of specialty sulfones for pharmaceutical intermediates due to the stability imparted by the sulfone group.
