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, fungi, and spores.

In water treatment, including cooling towers, industrial water systems, and oil and gas operations, it serves as a biocide to control microbial growth. It is also utilized in the leather tanning industry as a cross-linking agent to improve the durability and quality of leather products.

Additionally, glutaraldehyde is employed in histology and pathology labs for tissue fixation, preserving cellular structures for microscopic examination, including light and electron microscopy. Its cross-linking properties make it valuable in various industrial applications, including the production of adhesives, coatings, and polymers.

However, glutaraldehyde should be handled with care as it can cause skin irritation, respiratory issues, and allergic reactions. Proper ventilation and protective equipment are recommended.
