Methyl 3-oxopentanoate, also known as diethyl malonate or MEAM, is frequently employed as a building block in the synthesis of various organic compounds, including pharmaceuticals, agrochemicals, and flavoring agents. It also serves as a reagent in organic reactions, particularly in carbon-carbon bond formation through malonate synthesis. Furthermore, researchers are investigating the potential application of Methyl 3-oxopentanoate in the development of chiral auxiliaries, compounds that assist in selectively controlling the stereochemistry of chemical reactions.
