English description（英文原文，共 932 字符）
Product Name:Niacin
English Name:Niacin
CAS No.:59-67-6
Aliases:Vitamin B3, Nicotinic acid, 3-Pyridinecarboxylic acid
Molecular Formula:C6H5NO2
Physical Properties:White crystalline or crystalline powder, odorless or slightly characteristic odor, slightly acidic taste. Freely soluble in boiling water and boiling ethanol, soluble in water and ethanol, slightly soluble in ether, practically insoluble in chloroform. Melting point 236-239°C, sublimes at high temperature. Aqueous solution is acidic.
Uses:Niacin is one of the B vitamins, involved in lipid metabolism, tissue respiration oxidation and anaerobic glycolysis. It is used for preventing and treating niacin deficiency such as pellagra, and also used as a nutritional fortifier in food and feed additive.
Technical Specifications:
Assay (on dry basis) ≥99.0%
Melting point 234-238°C
Loss on drying ≤0.5%
Residue on ignition ≤0.1%
Heavy metals (as Pb) ≤10mg/kg
