2-Chloronicotinic acid Chemical Properties,Usage,Production
Chemical Properties
white to cream powder. MP>175°C (decomposition), insoluble in water, soluble in organic solvents such as benzene and toluene.
Uses
2-Chloronicotinic Acid is used in the preparation of 4-thiazolidinone derivatives and Schiff bases displaying antimicrobial activity.
Application
2-Chloronicotinic acid is used in the synthesis of the anti-inflammatory and analgesic pralofen. It is an intermediate of the herbicides nicosulfuron and diflufenican. It is also used as pharmaceutical intermediates for the manufacture of mefenamic acid, niflumic acid, etc.
Preparation
Chloronicotinic acid was synthesized from nicotinic acid by oxidation by H2O2 and then chlorinationby POCl3 and PCl5 in a yield of 87.5%.
Synthesis of 2-chloronicotinic acid: Pour chlorine gas into the mixed solution of phosphorus oxychloride and phosphorus trichloride, control the temperature at about 60°C, until the remaining chlorine gas escapes, cool and add nicotinic acid N-oxide in batches, and heat the mixed solution. The reaction was carried out at 100-105°C for 1-1.5 h, and the reaction mixture was stirred for 30 min after the reaction mixture was transparent, and phosphorus oxychloride was removed under reduced pressure. The obtained residue was cooled to room temperature, and water was added to obtain the finished product of 2-chloronicotinic acid.
Definition
ChEBI: 2-Chloronicotinic acid is an aromatic carboxylic acid and a member of pyridines.
