What is a Ethylene oxide (C₂H₄O)?

Ethylene oxide (C₂H₄O) is a colorless, flammable gas with a slightly sweet, ether-like odor and a cyclic ether structure. It is primarily used for sterilizing medical equipment and as a chemical intermediate. Its strong antimicrobial properties allow it to effectively sterilize items at low temperatures, making it ideal for use on heat-sensitive plastic instruments.

In the chemical industry, ethylene oxide is also used to produce ethylene glycol, which is a key ingredient in antifreeze and polyester resins. Despite its usefulness, ethylene oxide is highly toxic, and exposure via inhalation or skin contact can pose serious health risks. It is classified as a carcinogen, and its use is strictly regulated in many countries to ensure safety.
