Glutaraldehyde is widely used as a disinfectant and sterilizing agent, particularly 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 applied to control microbial growth in cooling towers and pipelines. Additionally, glutaraldehyde is used in the tanning industry to cross-link collagen fibers in leather, improving its durability and resistance to heat and chemicals. It also serves as a fixative in biological research, preserving cellular structures for microscopy and histology studies. In the oil and gas industry, it is utilized as a biocide to prevent microbial contamination in drilling fluids and pipelines.
