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 and agrochemicals. Its ability to act as a protecting group for carboxylic acids and amines makes it valuable in complex molecule synthesis. Additionally, it is employed in the development of specialty chemicals and fine chemicals, where precise control over reaction pathways is essential. Its stability and reactivity under mild conditions make it a preferred choice in various industrial and laboratory applications.
