Application: Nicotinic acid. It is a precursor of the coenzymes NAD and NADP. Widely distributed in nature; appreciable amounts are found in liver , fish, yeast and cereal grains. Dietary deficiency is associated with pellagra. The term “niacin” has also been applied.
Niacin feed grade is used as vitamin for poultry, swines, ruminants, fish, dogs and cats, etc. It is also used as intermediate for nicotinic acid derivatives and technical applications.
Niacin USP is used for food fortification, as dietary supplement and as an intermediate of pharmaceuticals. |
