Methylammonium formate is an ionic liquid consisting of methylammonium (CH₃NH₃⁺) as the cation and formate (HCOO^–) as the anion.^[1] This salt can be formed by the reaction between methylamine (CH₃NH₂) and formic acid (HCOOH). It has characteristics of both an ammonium salt and a formate salt. It is soluble in water,^[2] as well as other polar solvents.
