3-BROMO-5-HYDROXYBENZOIC ACID Chemical Properties,Usage,Production
Description
3-Bromo-5-hydroxybenzoic acid is a polyfunctional benzoic acid compound. Its molecular structure contains a hydroxyl group, a carboxyl group and a bromine atom, which are key to the substance’s high chemical reactivity; it can be used in various chemical reaction systems, including substitution, transposition and esterification. Furthermore, it can serve as a pharmaceutical intermediate in the preparation of active substances such as Cbl-b inhibitors.
Uses
3-Bromo-5-hydroxybenzoic acid is a carboxylic acid derivative and is used in organic synthesis.
Synthesis Reference(s)
[1] Leukotriene b4 inhibitors. Patent no. US20100240678A1
Hazard
3-Bromo-5-hydroxybenzoic acid is toxic when ingested and is highly toxic to aquatic organisms.
Synthesis
To a solution of NaOH (12.2 g; 305.8 mmol) in 300 mL of water was added 3-bromo-5-iodo-benzoic acid (20 g, 61.2 mmol) and Cu2O (866 mg, 6.1 mmol). The reaction mixture was heated at 100° C. for 24 h. After complete consumption of the starting material, the reaction mixture was cooled to room temperature and filtered through celite. The filtrate was then acidified with 10% aq. HCl and extracted into ethyl acetate. The organic extract was dried over anhydrous sodium sulfate and concentrated under reduced pressure to afford the 3-Bromo-5-hydroxybenzoic acid as a tan solid (12.3 g, 93% yield).
Purification Methods
The acid crystallises from H2O (m 238-239o), and with Me2SO4 it yields the 3-methoxy derivative with m 190-191o (from EtOH). [Baddar et al. J Chem Soc 469 1955, Beilstein 10 IV 333.]
