Methyl 5-Hexenoate is primarily used as an intermediate in organic synthesis, particularly in the production of flavors and fragrances. Its unsaturated ester structure makes it valuable for creating complex molecules with fruity or floral notes. It is also employed in polymer chemistry as a monomer or co-monomer for synthesizing specialized polymers with unique properties. Additionally, it serves as a building block in the synthesis of pharmaceuticals and agrochemicals, where its reactive double bond allows for further functionalization. In research, it is utilized to study reaction mechanisms and develop new synthetic pathways.
