CH3OCH2CH3

CH3OCH2CH3 is an organic ether with the formula C3H8O. Its structure consists of a methyl group (CH3) bonded to an oxygen atom, which is connected to an ethyl group (CH2CH3). The compound is commonly referred to as methyl ethyl ether, and its systematic IUPAC name is 1-methoxyethane.

In terms of properties, methyl ethyl ether is a volatile, flammable liquid at room temperature with a characteristic ether-like odor. Like other simple ethers, it has relatively low polarity and can dissolve many nonpolar and moderately polar organic compounds. It is typically used as a solvent in organic synthesis and in various industrial applications where a moderately nonpolar, low-boiling solvent is desired.

Preparation and reactions, methyl ethyl ether can be prepared by the Williamson ether synthesis, for example from sodium methoxide and ethyl halide (ethyl bromide or chloride), giving CH3OCH2CH3. Ethers are generally resistant to many reactions but can be cleaved by strong acids or undergo oxidation under harsh conditions. A practical safety note is that many ethers form peroxides upon prolonged storage in air and light, so appropriate storage and handling practices are important. They are also highly flammable and should be kept away from sources of ignition.

Applications and considerations: as a solvent, methyl ethyl ether is used for processes requiring a relatively nonpolar, low-boiling medium. Its use has declined in some applications due to safety concerns common to many ethers, but it remains a recognized chemical in certain organic synthesis protocols.
