Low boiling point
Evaporates at about 35 °C, so it is easy to remove after extraction or reaction.

Product overview & key benefits
Diethyl ether (ethoxyethane) boils at about 35 °C and dissolves fats, oils, waxes and many organic compounds, so it is used for extraction and as a reaction solvent — for Grignard reactions in particular — in pharmaceutical and fine-chemical plants. It is also used as a solvent in medicine production and as a raw material for detergents.
Diethyl ether is extremely flammable, forms explosive peroxides on storage, and is a controlled precursor chemical under the UN 1988 Convention, so export and import need permits in China and in many destination countries. Tell us your end use and licence status when you inquire.
Dry, high-purity grade
≥ 99.5% (GC) with water ≤ 0.05% (KF) suits moisture-sensitive reactions.
Specified on your terms
We quote against your purity, water and peroxide limits and send the batch COA for each lot.

Selection & comparison
Choosing the right diethyl ether grade
| Your requirement | What usually works |
|---|---|
| Grignard and moisture-sensitive reactions | Dry grade: water ≤ 0.05% (KF) |
| Long storage or repeated opening | Ask for a stabilized grade (e.g. with BHT) |
| Extraction | Specify residue on evaporation |
| Replacing an existing supplier | Send your current TDS or COA; we quote against the parameters you approve |
Packaging & storage
Packaging
Tell us the drum size you need; packaging must be UN-approved for Class 3, PG I.
Storage
Store in closed containers, cool and away from light and ignition sources. Ether forms explosive peroxides — date opened containers and test for peroxides before distilling.
Transport
Highly flammable liquid (UN 1155, Class 3, PG I). Shipped under our precursor-chemical export licence.
From first email to approved supply
Name the end use
Synthesis, extraction or raw material, and the end-user — permits depend on it.
Compare the numbers that matter
Purity (GC), water (KF), peroxide and residue on evaporation.
Check permits first
We hold the export licence. Confirm whether your country needs an import permit and send it with your order; this sets the lead time.
Trial, then lock the spec
Run a sample in your own process and keep the approved lot COA as the reference for contract limits.
Tell us your requirement. We match the grade.
Tell us your end use and whether you hold an import permit, the quantity and the destination port. Add your current specification and we will quote against it.
