CAS 79-21-0: Peracetic acid

Description: Peracetic acid, with the CAS number 79-21-0, is a colorless liquid with a pungent, vinegar-like odor. It is an organic peroxide and is classified as a strong oxidizing agent. Its chemical formula is C2H4O3, and it is often used as a disinfectant, sanitizer, and bleaching agent in various industries, including food processing and water treatment. Peracetic acid is highly soluble in water and can decompose exothermically, releasing acetic acid and oxygen, which necessitates careful handling and storage. It exhibits antimicrobial properties, making it effective against bacteria, viruses, and fungi. However, it can be corrosive to skin and eyes, and its vapors can irritate the respiratory system. Due to its reactivity, it should be stored away from reducing agents and incompatible materials. Overall, peracetic acid is valued for its efficacy in sterilization and disinfection, but safety precautions are essential when using this potent chemical.
