Peracetic acid is a peroxy acid that is acetic acid in which the OH group is substituted by a hydroperoxy group. It is a versatile oxidising agent that is used as a disinfectant. Peracetic acid is a colorless liquid with a strong, pungent acrid odor. Used as a bactericide and fungicide, especially in food processing; as a reagent in making caprolactam and glycerol; as an oxidant for preparing epoxy compounds; as a bleaching agent; a sterilizing agent; and as a polymerization catalyst for polyester resins.
