Used as a reagent in organic synthesis, particularly in lithium enolate chemistry for carbon-carbon bond formation. It serves as a source of nucleophilic enolates in aldol-type reactions and Michael additions. Commonly employed in pharmaceutical intermediates synthesis where controlled enolization is required. Also utilized in coordination chemistry as a ligand precursor due to its ability to chelate metal ions. Its solubility in polar aprotic solvents makes it suitable for use in homogeneous reaction conditions.
