2-Fluoro-4-methoxybenzoic acid (2FMBA) is a potent antimicrobial agent that inhibits the growth of bacteria, fungi and other microorganisms. 2FMBA has significant antibacterial activity against Gram-positive and Gram-negative bacteria and also has significant antifungal activity against Candida albicans. 2FMBA is active in the presence of light and is a strong acid. It can be synthesized by refluxing benzoic acid with hydrazine, or by reacting an aromatic carboxylic acid with oxychloride. 2FMBA is used to treat bacterial infections such as E. coli, Staphylococcus, Salmonella, Shigella and Mycoplasma; fungal infections such as Candida albicans; and protozoal infections such as Giardia lamblia.
