Boiling point: 150-160 º C
Water solubility: 1000g / L (20 º C)
Flash point: 182 º C
Property Description: White needle like crystal or powder. The melting point is 129-131 ℃. 1g of the product is soluble in 1ml water, 1.5ml alcohol and 10ml glycerol, insoluble in ether. It tastes bitter.
Product application: Nicotinamide and nicotinic acid are commonly used in most cases, and nicotinic acid also produces nicotinamide in animals. When the body lacks nicotinic acid and nicotinamide, it will get pellagra. So they can prevent pellagra. They play a role in the metabolism of protein and sugar and improve the nutrition of human and animals. In addition to medicine, it is also widely used as food and feed additives. The world’s production capacity has exceeded 30000 tons. In Japan, nicotinamide is used in medicine for 40% and feed additives for 50%. Food additives accounted for 10. Nicotinic acid and nicotinamide are nontoxic. They are mostly contained in animal liver, kidney, yeast and rice sugar. The LD50 of nicotinamide injected subcutaneously to rats is 1.7 g / kg. Index name index content ≥ 99 melting point 128.0-131.0 ℃ pH 5.5-7.5
