Glutaraldehyde (saturated dialdehyde) is a commonly used high-level disinfectant/sterilant. When aqueous solutions of 2% glutaraldehyde are alkalized ("activated") to a pH between 7.5 and 8.5, glutaraldehyde can kill vegetative bacteria, M. tuberculosis, fungi, viruses, and spores in less than 10 min (see Table 4-3). This sporicidal activity qualifies glutaraldehyde as a true steri-lizing agent.
