CH3NH32SO4

Methylammonium sulfate, with the chemical formula CH3NH32SO4, is an inorganic salt. It is formed from the reaction of methylamine, a primary amine, with sulfuric acid. The compound consists of two methylammonium cations (CH3NH3+) and one sulfate anion (SO42-). In its pure form, methylammonium sulfate is typically a white crystalline solid.

Methylammonium sulfate can be synthesized by carefully mixing stoichiometric amounts of methylamine and sulfuric acid in a suitable solvent, such as water. The reaction is exothermic, and cooling may be required. After the reaction, the salt can be isolated through evaporation of the solvent and subsequent crystallization.

This compound has found applications in various fields. In materials science, it has been explored as a precursor for the synthesis of hybrid organic-inorganic perovskites, which are of interest for photovoltaic and optoelectronic devices. The methylammonium ion is a common component in these perovskite structures. Methylammonium sulfate can also serve as a source of methylammonium ions in other chemical syntheses or research applications. Its properties, such as solubility and reactivity, depend on factors like temperature and the presence of other chemicals.
