Used as an intermediate in organic synthesis, particularly in the preparation of guanidine derivatives which are important in pharmaceuticals and agrochemicals. It serves as a reagent for introducing the guanidine functional group into molecules, enhancing biological activity in drug design. Commonly applied in the synthesis of nitrogen-containing heterocycles and active pharmaceutical ingredients (APIs). Its reactivity allows for efficient conversion under mild conditions, making it valuable in research and development laboratories for constructing complex organic molecules.
