white to light yellow crystal powder. soluble in organic solvents such as benzene, toluene, ketone and ether.The corresponding 2-fluorobenzoyl chloride can be obtained by reacting 2-fluorobenzoic acid with an acid chloride agent such as SOCl2, PCl3, etc.??
2-Fluorobenzoic acid may be employed in the preparation of zaragozic acid A analogs. It is also used as an organic chemical synthesis intermediate.??
2-Fluorobenzoic acid is an intermediate of the fungicide tritriazole and meclofenamic acid.??
ChEBI: 2-fluorobenzoic acid is a 2-halobenzoic acid that is benzoic acid carrying a fluoro substituent at position 2. It is a fluorobenzoic acid and a 2-halobenzoic acid. It is a conjugate acid of a 2-fluorobenzoate.?? ??
The preparation of 2-fluorobenzoic acid is based on anthranilic acid as raw material, adding anhydrous hydrogen fluoride and sodium nitrite in methoxyethyl methyl ether solvent for diazotization, refluxing for 3 hours, and post-processing to obtain the finished product.Purification Methods
Crystallise the acid from 50% aqueous EtOH, dilute HCl or *C6H6, then purify it by zone melting or vacuum sublimation at 130-140o. [Beilstein 9 H 333. 9 III 1324, 9 IV 950.]2-??????? ?? ?? ? ???
