Used primarily as an intermediate in organic synthesis, particularly in the production of pharmaceuticals and agrochemicals. It serves as a building block for ester and ketone derivatives due to its active methylene group, enabling condensation reactions. Also utilized in the fragrance industry for creating fruity aroma compounds, especially in flavor formulations that mimic apple, pineapple, and other sweet fruit notes. Its reactivity makes it suitable for use in Claisen and aldol condensations to form more complex molecules.
