Used primarily as an intermediate in the synthesis of pharmaceuticals, particularly in the production of antidiabetic drugs such as metformin. It serves as a key building block due to its guanidine structure, which is essential for biological activity in several therapeutic agents. Also employed in the development of agrochemicals and functional materials where a substituted guanidine moiety is required. Its reactivity and solubility profile make it suitable for use in aqueous and organic reaction systems, facilitating its incorporation into larger molecules under mild conditions.
