Used in biochemical research as a metabolite analog of niacin (vitamin B3), N-Ethylnicotinamide helps study nicotinamide metabolism and related enzymatic pathways. It serves as a probe to investigate the activity of enzymes such as nicotinamide N-methyltransferase and aldehyde oxidase. Due to its structural similarity to nicotinamide, it is also employed in experiments assessing cellular redox processes and energy metabolism. Additionally, it has been explored in pharmacological studies for its potential effects on metabolic regulation and detoxification mechanisms.
