Used primarily in biochemical research to study alcohol metabolism and its effects on the body. It plays a critical role in detoxifying aldehydes generated during alcohol breakdown, making it essential in understanding conditions like alcohol flush reaction and liver diseases. In medical diagnostics, it helps assess liver function and alcohol-related disorders. Additionally, it is utilized in industrial applications for the synthesis of certain chemicals and pharmaceuticals, particularly in processes requiring aldehyde conversion. Its role in cellular protection against oxidative stress is also a focus in studies related to aging and neurodegenerative diseases.
