Methyl 3-butenoate is widely used in the synthesis of various organic compounds, particularly in the production of fragrances and flavoring agents. Its ester functional group makes it a valuable intermediate in creating esters with fruity or floral aromas, which are essential in the cosmetics and food industries. Additionally, it serves as a building block in organic chemistry for the preparation of more complex molecules, including pharmaceuticals and agrochemicals. Its reactivity in polymerization reactions also makes it useful in the development of specialty polymers and coatings.
