Methylglyoxal is widely used in the food industry as a flavoring agent, particularly in products like caramel and roasted coffee, where it contributes to the characteristic aroma and taste. In the medical field, it is studied for its potential role in advanced glycation end-products (AGEs) research, which is crucial for understanding diabetes and aging-related diseases. Additionally, it serves as a precursor in the synthesis of various pharmaceuticals and organic compounds. In biochemistry, methylglyoxal is utilized as a tool to study cellular stress responses and metabolic pathways. Its antimicrobial properties also make it valuable in developing disinfectants and preservatives for industrial and cosmetic applications.
