Widely used as a disinfectant and sterilant, glutaraldehyde standard solution is essential in healthcare settings for cold sterilization of medical devices such as endoscopes, surgical instruments, and dialysis equipment due to its broad-spectrum antimicrobial activity against bacteria, viruses, fungi, and spores. It is also employed in water treatment systems to control microbial growth in industrial cooling towers and oilfield operations. In histology and pathology labs, it serves as a tissue fixative for electron microscopy, preserving cellular structures with high fidelity. Additionally, it finds use in the tanning industry for cross-linking collagen fibers in leather processing and in bioconjugation techniques for immobilizing proteins or enzymes in diagnostic and research applications. Its role as a standard solution also supports calibration and quality control in analytical testing.
