|  |  | 3-Fluoro-4-hydroxybenzoic acid Usage And Synthesis | 
 | Chemical Properties | Yellow solid |  | Uses | 3-Fluoro-4-hydroxybenzoic acid may be used in the preparation of (S)-2-methylbutyl-3-fluoro-4-hydroxy benzoate and 4-n-alkoxy-3-fluorobenzoic acids. It may also be used in the synthesis of bis 3-fluoro-4-hydroxybenzoates, which are potent KCa2/3 pan-inhibitors. |  | General Description | 3-Fluoro-4-hydroxybenzoic acid is a halo-substituted 4-hydroxybenzoic acid that can be prepared from 3-fluoro-4-methoxybenzoic acid via demethylation. |
