Ethylammonium nitrate or ethylamine nitrate[3] (EAN) is a salt with formula [CH3CH2NH3]+[NO3]−. It is an odorless and colorless to slightly yellowish liquid with a melting point of 12 °C.[4] This compound was described by Paul Walden in 1914,[5][6] and is believed to be the earliest reported example of a room-temperature ionic liquid.[7]
