What is the primary chemical sterilization compound used to sterilize endoscopic instrumentation and scopes?

Peracetic acid is a highly effective sterilizing agent commonly used for the chemical sterilization of endoscopic instrumentation and scopes. It is favored for its ability to kill a broad spectrum of microorganisms, including bacteria, viruses, and spores, in a short amount of time. Its efficacy in the presence of organic material further enhances its suitability for medical equipment that may be difficult to clean thoroughly prior to sterilization.

Peracetic acid acts by oxidizing cellular components of the microorganisms, rendering them inactive. This compound is often used in a liquid form or in an automated system specifically designed for the sterilization of heat-sensitive instruments, making it ideal for endoscopes and similar devices.

While other chemical agents listed have their applications in disinfection or cleaning, they do not offer the same broad-spectrum sterilization capabilities required for delicate and complex surgical instrumentation like endoscopes.
