Description

General description

Peracetic acid (PAA) is a peroxy acid that is commonly used as an excellent oxidizing agent in organic synthesis. It is also used as a bleaching and sterilizing agent.

Application

Peracetic acid solution (32 wt. % in dilute acetic acid) can be used as an oxidant for the selective epoxidation of aliphatic terminal alkenes in the presence of manganese(II) perchlorate as the catalyst at ambient temperature. It is also used to oxidize sulfides, selenides, and amines.
