Used as an intermediate in organic synthesis, particularly in the development of pharmaceuticals and agrochemicals. Its structure supports the formation of nitrogen-containing heterocycles, which are common motifs in bioactive molecules. It also serves in the preparation of functionalized guanidine derivatives that exhibit biological activity, including antimicrobial and antiviral properties. Additionally, it finds use in research settings for modifying peptides and proteins due to its ability to react selectively under mild conditions.
