Used as a versatile reagent in organic synthesis, particularly in the preparation of Weinreb amides, which are intermediates for the synthesis of ketones and aldehydes. It is also employed in the formulation of pharmaceuticals and agrochemicals, aiding in the creation of complex molecules. Additionally, it serves as a solvent in various chemical reactions due to its stability and ability to dissolve a wide range of compounds. Its role in peptide coupling reactions and as a protecting group for carboxylic acids further highlights its importance in synthetic chemistry.
