Used as a versatile reagent in organic synthesis, particularly in the preparation of amides and esters. It serves as a key intermediate in the production of pharmaceuticals, enabling the introduction of methoxy and methylamino groups into complex molecules. Additionally, it is employed in the development of agrochemicals and fine chemicals, where its reactivity facilitates the creation of specialized compounds. Its role in peptide coupling reactions is also notable, aiding in the synthesis of biologically active peptides.
