| use | 2-fluorobenzoic acid is an intermediate of fungicide triazolol. Used as an intermediate for medicine, pigments and dyes |
| production method | its preparation method is to use 2-aminobenzoic acid as raw material, add anhydrous hydrogen fluoride and sodium nitrite to methoxyethyl methyl ether solvent for diazotization, reflux for 3 hours, and carry out post-treatment to obtain the finished product. 2-fluorobenzoic acid is colorless crystal, m. p. 123~125 ℃, soluble in benzene, ketone, ether and other organic solvents. When 2-fluorobenzoic acid reacts with acylchlorinating agents such as SOCl2, PCl3, etc., the corresponding 2-fluorobenzoyl fluoride (2-fluoro benzoyl chloride) can be obtained. 2-Fluorobenzoyl chloride is also an intermediate of the fungicide powder zonazole.
