Glutaraldehyde is widely recognized for its efficacy as a high-level disinfectant, particularly in the context of manual processing of medical instruments such as endoscopes. It is a potent chemical that can effectively eliminate bacteria, viruses, fungi, and bacterial spores when used properly. Its ability to achieve high-level disinfection makes it suitable for reusable medical devices that require thorough sterilization processes, particularly in settings where heat-based sterilization methods may not be feasible.

Glutaraldehyde works by cross-linking proteins in microbial cells, which ultimately leads to cell death. A common concentration used for high-level disinfection is 2-3%, typically achieved through soaking instruments for a specified duration to ensure complete disinfection. This method is critical in healthcare environments where the prevention of infection is paramount.

While the other chemicals listed, such as formaldehyde and hydrogen peroxide, have their uses, they either have different applications or may not be as effective as glutaraldehyde for certain types of disinfection. Alcohol, while useful for surface cleaning and lower-level disinfection, does not achieve the same level of efficacy against spores and certain pathogens as glutaraldehyde does. Understanding the role of glutaraldehyde in infection control routines is essential for maintaining a safe
