Glutaraldehyde is widely used as a high-efficacy disinfectant and sterilizing agent in medical, dental, and industrial settings. It effectively kills bacteria, viruses, and fungi, serving as a key component for sterilizing surgical instruments, endoscopes, and other medical tools. In water treatment, it controls microbial growth in cooling systems. It also acts as a fixative in histology, pathology labs, and embalming fluids, preserving biological tissues and preventing decomposition for microscopic examination or body preservation. In various industries, including leather tanning, paper production, and textiles, it improves material durability, strength, and quality.
