This compound was described by Paul Walden in 1914, and is believed to be the earliest reported example of a room-temperature ionic liquid.
In particular he invented the stereochemical reaction known as Walden inversion and synthesized the first room-temperature ionic liquid, ethylammonium nitrate.
