L-Canavanine Sulfate Hydrate is primarily used in biochemical research to study its role as a natural amino acid analog. It is often employed to investigate its effects on cellular processes, particularly in plants and microorganisms, where it can inhibit certain enzymes and disrupt protein synthesis. This compound is also utilized in studies related to its potential anticancer and antiviral properties, as it can interfere with the growth of certain cancer cells and viruses. Additionally, it serves as a tool in plant biology to understand its role as a defense mechanism against herbivores and pathogens. Researchers also explore its impact on nitrogen metabolism and its potential as a natural herbicide.
