2-Chloronicotinic acid is a white or original white crystalline powder with a melting point of 176-178 ℃. 2-Chloronicotinic acid, as an important pharmaceutical and pesticide intermediate, produces a byproduct of 6-chloronicotinic acid during the production process. If the content of 6-chloronicotinic acid is too high, it will seriously affect the quality of subsequent products, so it is very important to determine the content of 2-chloronicotinic acid. In recent years, with the development of pesticides and pharmaceutical science, the nicotinic acid series of chemicals has received increasing attention and application. Among them, 2-chloronicotinic acid is used as an agricultural and medical intermediate to prepare new and efficient herbicides, as well as highly effective anti-inflammatory and analgesic drugs such as niflumic acid and praprofen. These products are in short supply both domestically and internationally.
