Used in biochemical research as a metabolite of nicotinamide, 1-Methylnicotinamide chloride serves as a marker for nicotinamide metabolism and is studied for its potential role in cellular energy processes. It has been investigated for anti-inflammatory and vasoprotective effects, particularly in relation to endothelial function. Researchers also explore its involvement in kidney function and oxidative stress regulation. Due to its solubility and stability, it is commonly used in in vitro and in vivo studies focusing on metabolic pathways and neuroprotection.
