2-Chloroethanol is a chemical compound with the formula HOCH2CH2Cl and the simplest chlorohydrin.
While 2-chloroethanol is also sometimes referred to simply as "chloroethanol", the same term can also be used for the less known and less stable 1-chloroethanol isomer.
2-Chloroethanol is a colorless liquid, miscible with water and organic solvents.
2-Chloroethanol is sold by chemical suppliers, though it's not cheap or easy to acquire.
It is classified as an extremely hazardous substance in the United States as defined in Section 302 of the U.S. Emergency Planning and Community Right-to-Know Act (42 U.S.C. 11002), and is subject to strict reporting requirements by facilities which produce, store, or use it in significant quantities.

- Preparation of glycol ethers (2-methoxyethanol and 2-ethoxyethanol)
2-Chloroethanol is very toxic, with an estimated LD50 of 81-89 mg/kg in rats. It can also absorb through skin contact, and thus proper protection like chemically resistant gloves must be worn when handling the compound.
In closed bottles, with a clear hazardous chemical label, in well ventilated locations.
To neutralize this compound, you may use Fenton's reagent. Avoid using KOH to hydrolyze the compound, as the neutralization reaction will produce the highly volatile, extremely flammable and carcinogenic ethylene oxide, which is a severe explosion hazard.
