High Purity Dimethylammonium Bromide (DMABr, C2H8BrN), 99.5%, 3g

Dimethylammonium Bromide (DMABr) is a popular additive in Bromide based perovskite materials (ABX3), such as CsPbBr3, to improve the stability of perovskite by tuning the morphology and crystallization of the perovskite crystals. It is also a precursor of didodecyl dimethyl ammonium bromide (DDAB), which is another additive of perovskite solar cells that provides a hydrophobic layer on top of the perovskite layer, which reduces the direct contact between the perovskite and moisture to improve the moisture resistance.
