Product Overview
High Purity Ethylene Oxide (EtO), also known as oxirane, is a cyclic ether with the chemical formula C₂H₄O. It is a colorless, highly reactive substance used as a chemical intermediate and, under strictly controlled conditions, as a sterilizing agent for compatible medical devices and other products.
Ethylene oxide's reactivity enables the production of chemicals such as ethylene glycol and various ethoxylated compounds. In sterilization applications, it can inactivate microorganisms by reacting with biological molecules, making it suitable for selected heat- or moisture-sensitive products when validated sterilization processes are used.
Product selection depends on the application, required purity, individual impurity limits, moisture specifications, and delivery configuration. Buyers should verify the current technical data sheet and Certificate of Analysis (CoA) to ensure the product meets the relevant process, quality, and regulatory requirements.
