3-Pyridinecarboxamide, also known as Nicotinamide (Niacinamide), is an important vitamin B3 derivative and pharmaceutical ingredient. It is widely used in pharmaceuticals, cosmetics, nutrition supplements, and animal feed additives. It functions as a precursor of NAD/NADP coenzymes in biological systems and is commonly used for vitamin supplementation, skin care formulations, anti-aging products, whitening products, and pharmaceutical preparations. It is also used as an intermediate in biochemical and chemical synthesis.
