Widely used as a disinfectant in healthcare settings, especially for high-level disinfection of heat-sensitive medical instruments such as endoscopes, dialysis equipment, and respiratory therapy devices. It effectively kills bacteria, viruses, fungi, and spores, making it suitable for sterilization processes where steam autoclaving is not possible. Commonly used in cold sterilization baths due to its ability to maintain efficacy over extended exposure times. Also applied in water treatment systems to control microbial growth in industrial cooling towers and in the preservation of tissue samples in histology and electron microscopy. Its cross-linking properties make it valuable in fixing biological specimens for laboratory analysis. Used in some dental practices for surface disinfection and instrument processing. Due to its strong biocidal activity, it is also found in veterinary and agricultural settings for disinfecting equipment and facilities.
