The pharmaceutical industry refers to companies that research, manufacture, or sell small-molecule (chemical-based) or large-molecule (biological-based) drugs. Maintaining hygienic conditions is a critical part of pharmaceutical research and production. Vaporized hydrogen peroxide (H₂O₂) is often used as a decontaminating agent for materials that cannot withstand high temperatures—such as laboratory or manufacturing equipment, pill bottles, and syringes. However, if residual (post aeration) H₂O₂ levels remain too high, they can adversely affect drug stability, efficacy, and safety. Therefore, residual H₂O₂ levels must be periodically or continuously monitored at ppb levels to ensure drug stability, efficacy, and safety.
