Used primarily as a reactive intermediate in organic synthesis, this compound serves as a building block for pharmaceuticals and agrochemicals. Its strained oxazolone ring and vinyl group enable cycloaddition and nucleophilic ring-opening reactions, making it valuable in constructing complex heterocyclic systems. It is also employed in the development of specialty polymers and functional materials due to its ability to undergo polymerization or act as a cross-linking agent. Its reactivity profile allows for selective modifications under mild conditions, which is advantageous in multi-step synthetic routes.
