Unlike alcohols, ethers are fairly unreactive (except towards combustion).
They are very common organic solvents, and some ethers also make good anesthetics.
Simple ethers are named by naming the alkyl groups in alphabetical order and adding the word "ether" to the end.

For example, a methyl group attached to an oxygen, OCH3, is named as a methoxy group.

Ethyl Diglyme (Diethylene Glycol Methyl Ethyl Ether) has relatively low acute toxicity, but prolonged or high-level exposure could lead to more significant health concerns.
Care should be taken to prevent spills and leaks, as it can cause environmental contamination if released in significant quantities.
Moderately toxic by ingestion.
Ethyl Diglyme (Diethylene Glycol Methyl Ethyl Ether) an experimental teratogen.
Other experimental reproductive effects.
Flammable when exposed to heat or flame.
When heated to decomposition Ethyl Diglyme (Diethylene Glycol Methyl Ethyl Ether) emits acrid smoke and irritating fumes.
The European Chemicals Agency lists diglyme as a substance of very high concern (SVHC) as a reproductive toxin.
At higher temperatures and in the presence of active metals diglyme is known to decompose, which can produce large amounts of gas and heat.
This decomposition led to the T2 Laboratories reactor explosion in 2007.
Similar to other glycol ethers, Ethyl Diglyme (Diethylene Glycol Methyl Ethyl Ether) can be hazardous upon prolonged exposure.
