Aminoguanidine hemisulfate salt is widely used in biochemical research as an inhibitor of advanced glycation end-products (AGEs). It helps in studying the role of AGEs in diabetes and aging-related diseases by preventing the formation of these harmful compounds. Additionally, it is employed in the synthesis of various heterocyclic compounds, which are important in pharmaceutical development. Its ability to act as a nitric oxide synthase inhibitor also makes it valuable in cardiovascular and neurological research, providing insights into conditions like hypertension and neurodegenerative disorders. Furthermore, it is utilized in the production of dyes, resins, and other industrial chemicals due to its reactive guanidine group.
