Peroxybenzoic acid is a simple peroxy acid. It may be synthesized from benzoic acid and hydrogen peroxide,^[2] or by the treatment of benzoyl peroxide with sodium methoxide, followed by acidification.^[3]

Like other peroxyacids, it may be used to generate epoxides, such as styrene oxide from styrene:^[4]
