Description and Uses

Manganese(II) sulfide, MnS, occurs in nature as the mineral alabandite (isometric), rambergite (hexagonal), and the recently found browneite (isometric, with sphalerite-type, ZnS, structure, extremely rare and is only known from a meteorite). Manganese(II) sulfide can be formed through the reaction of a manganese(II) salt (such as manganese(II) chloride) with ammonium sulfide.

it is used as an intermediate in chemical research& pharmaceutical research.
