Chemical vapor sterilization uses which chemical in its cycle?

Explanation:
Chemical vapor sterilization relies on a formaldehyde-based vapor to sterilize instruments. The heated formaldehyde gas penetrates wrapped items and denatures proteins, killing microorganisms during the cycle. Water vapor is used in steam sterilization (autoclaves), not CVS. Oxygen and chlorine gas are not the active sterilants in this process. The formaldehyde-based vapor is chosen because it effectively sterilizes at a relatively low temperature and works well with a variety of instruments.
