Glutaraldehyde is widely used as a disinfectant and sterilizing agent in medical and dental settings. It is effective in sterilizing surgical instruments, endoscopes, and other heat-sensitive medical equipment due to its ability to kill bacteria, viruses, and spores. In water treatment, it is employed as a biocide to control microbial growth in cooling towers and pipelines. Additionally, it is used in the tanning industry as a cross-linking agent for leather, improving its durability and resistance to moisture. In histology and pathology labs, glutaraldehyde is utilized as a tissue fixative, preserving cellular structures for microscopic examination. It also finds application in the oil and gas industry as a biocide in drilling fluids to prevent microbial contamination.
