Glutaraldehyde is commonly used as a high-level disinfectant for medical instruments and equipment, particularly in situations where sterilization is not possible. However, it is not appropriate for use as an environmental disinfectant. This is primarily because glutaraldehyde can be toxic if used improperly, potentially releasing harmful fumes and requiring specific handling and disposal procedures. Its effectiveness is also limited to applications where prolonged contact with surfaces is needed for disinfection to occur.

In contrast, other disinfectants listed have broader uses as environmental disinfectants. Hydrogen peroxide, for instance, is effective at killing a variety of pathogens and does not leave harmful residues. Chlorine dioxide is known for its efficacy against bacteria, viruses, and fungi, and is suitable for disinfecting environmental surfaces. Isopropyl alcohol, often utilized for disinfecting surfaces and skin, evaporates quickly and is effective against many microorganisms, making it safe and suitable for environmental use.
