Methylammonium halide

Generally they are white or light colored powders.

These salts are components of perovskite solar cells, which are being evaluated for commercialization.

Magneto-optical data storage concepts are also being testing based on various ammonium halides.

[2] These compounds are usually prepared by combining equimolar amounts of methylamine with the appropriate halide acid.

[3] These compounds' crystallography has been the subject of much investigation.
