Metylammoniumklorid

Metylammoniumklorid, known in English as methylammonium chloride, is an inorganic compound with the chemical formula CH3NH3Cl. It is a white crystalline solid that is highly soluble in water. The compound is formed by the combination of methylammonium cations (CH3NH3+) and chloride anions (Cl−).

Methylammonium chloride is often used in chemical research and industrial applications as a precursor or intermediate in the synthesis of other methylammonium compounds. It can also serve as a source of methylammonium ions in various chemical processes. Due to its properties, it finds relevance in the development of perovskite solar cells, where methylammonium ions are integral to the structure of hybrid organic-inorganic lead halide perovskites.

The compound can be prepared through the reaction of methylamine with hydrochloric acid, resulting in methylammonium chloride and water. Its melting point is approximately 302 °C, and it decomposes at higher temperatures.

In terms of safety, methylammonium chloride should be handled with care, as it can be irritating to skin and mucous membranes. Proper storage in a cool, dry place and adherence to safety protocols are recommended when working with this chemical.

Due to its specific chemical characteristics, methylammonium chloride continues to be of interest primarily within research settings, particularly in the fields of materials science and photovoltaics.
