3-Hydroxybenzoic acid CAS 99-06-9

3-Hydroxybenzoic acid simultaneously possesses both phenolic hydroxyl group and carboxyl group as dual functional groups, which has high chemical reactivity and can undergo reactions such as esterification, salification, and coupling. It is an important fine chemical intermediate. It has good thermal stability and does not deteriorate easily when stored at room temperature; the dust is irritating and inhalation of the dust should be avoided. 3-Hydroxybenzoic acid has low volatility and is unlikely to change color under normal storage conditions; however, it should not be stored together with strong bases or strong oxidants as they may react.
