Nicotinic acid CAS 59-67-6, chemical name pyridine-3-carboxylic acid, is an organic compound with the chemical formula C6H5NO2. It is a white crystalline powder, mainly present in animal viscera and muscle tissue, and also in trace amounts in fruits and egg yolks. It is one of the 13 essential vitamins for the human body. Niacin is mainly used as a feed additive, which can improve the utilization rate of feed protein, increase the milk production of cows, and increase the yield and quality of poultry and livestock meat such as fish, chicken, duck, cattle, and sheep. Niacin is also a widely used pharmaceutical intermediate, which can be used as a raw material to synthesize various pharmaceuticals, such as nicotinic acid and inositol nicotinate. In addition, niacin also plays an irreplaceable role in fields such as luminescent materials, dyes, and electroplating.
