Used as an intermediate in organic synthesis, particularly in the preparation of pharmaceutical compounds. It serves in the development of bioactive molecules due to the guanidine moiety, which is known for its strong hydrogen-bonding capability and polarity, enhancing interactions with biological targets. Commonly applied in research settings for designing enzyme inhibitors and receptor ligands. Also utilized in the synthesis of agrochemicals and functional materials where charged guanidinium groups improve solubility and stability.
