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]
