6-Chloronicotinic acid is used as building block for different chemical synthesis. Product Data Sheet | [Definition]
ChEBI: 6-Chloronicotinic acid is a member of pyridines and an aromatic carboxylic acid. | [General Description]
6-Chloropyridine-3-carboxylic acid is a metabolite of the neonicotinoid pesticides, imidacloprid and acetamiprid and occurs in different environmental matrices.(3) It is widely used in agricultural crop protection, domestic insect control and environmental pest management. | [Synthesis]
In a 1000ml flask, add 450g chlorobenzene, 100g 2-chloro-5-methylpyridine, and 3g catalyst cobalt acetate under stirring, heat the system to 80℃, introduce oxygen, and control the oxygen flow rate at 0.4L/min. React under this condition for 4 hours. After the reaction, cool the system to room temperature, filter, and dry to obtain a mixture of 119g 6-chloronicotinic acid and cobalt acetate. Place those mentioned above mixed crude product in a 1000ml flask, add 600g of recrystallization solvent methanol, stir and heat to reflux; wait for the 6-chloronicotinic acid crude product to dissolve completely, keep warm for 5min, slowly cool the system to 5℃, precipitate a white product, maintain this internal temperature and continue stirring for 1 hour, filter, wash the filter cake once with a small amount of cooled methanol, and dry the obtained damp product at 80℃ for 4 hours to obtain 98.5g 6-chloronicotinic acid, purity 99.52% (HPLC), yield 79.7%.
| [Purification Methods]
Purify it by recrystallisation from hot H2O and sublime it in a vacuum. [Pechmann & Welsch Chem Ber 17 2384 1884, Herz & Murty J Org Chem 26 122 1961, Beilstein 22/2 V 177.] |
