2- aMinoacid - Reference Information
| EPA chemical information | Information provided by: ofmpub.epa.gov (external link) |
| Overview | 2-aminonicotinic acid is an important pharmaceutical and pesticide intermediate. Traditionally, it is obtained by activating the pyridine ring, chlorination at the 2 position of the pyridine ring and hydroxylation. Due to the complexity of the synthetic circuit and low yield, the cost price is very high. At present, the price of 2-aminonicotinic acid remains high, which increases the cost burden on the promotion and use of its downstream products. |
