CAS 75-21-8: Ethylene oxide

Description: Ethylene oxide, with the CAS number 75-21-8, is a colorless, flammable gas at room temperature, characterized by its sweet odor. It is an epoxide, a cyclic ether with a three-membered ring structure, which makes it highly reactive. Ethylene oxide is primarily used as an intermediate in the production of antifreeze, surfactants, and various chemicals, including glycol ethers and polyethylene glycol. Due to its reactivity, it readily undergoes polymerization and can react with nucleophiles, making it valuable in organic synthesis. However, it is also a potent sterilizing agent, commonly employed in the medical industry for sterilizing equipment and supplies. Ethylene oxide is classified as a carcinogen and poses health risks upon exposure, necessitating stringent safety measures during handling and storage. Its boiling point is relatively low, and it can easily vaporize, contributing to its use in gaseous sterilization processes. Overall, while ethylene oxide is a versatile chemical with significant industrial applications, its hazardous nature requires careful management.
