Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and agrochemicals. It serves in the formation of carbamates and other nitrogen-containing compounds due to its ability to introduce both ethyl and phenylcarbamoyl groups. Commonly employed in reactions where controlled ester and amide bond formation is required, especially in heterocyclic compound synthesis. Its reactivity makes it suitable for use in research laboratories for developing active ingredients in crop protection agents and medicinal compounds.
