Methylammonium chloride in an organic halide with a formula of CH₃NH₃Cl. It is an ammonium salt composed of methylamine and hydrogen chloride. One potential application for the methylammonium halides is in the production of perovskite solar cells. ^{[3] [4]} The methyl group and other hydrogen atoms are bonded covalently to the nitrogen, with the chloride bonded ionically.
