What is a Peracetic acid (CH₃CO₃H)?

Peracetic acid (CH₃CO₃H) is a powerful oxidizing agent formed by the reaction of acetic acid (CH₃COOH) and hydrogen peroxide (H₂O₂). It is a colorless liquid with a strong, pungent odor and high volatility. Peracetic acid is an effective disinfectant and bleaching agent, widely used in various industries for its strong oxidizing properties.

Peracetic acid is particularly effective in sterilizing food processing equipment and surfaces, making it valuable in the food industry for hygiene management. It is also used in hospitals for sterilizing surgical tools and in water treatment to disinfect industrial wastewater. Despite its effectiveness, peracetic acid is highly corrosive and must be handled with care. High concentrations can cause irritation or damage to the skin and eyes, so protective equipment is essential when handling it. Peracetic acid also releases oxygen upon decomposition, making it useful in promoting oxidation-reduction reactions.
