Barium manganate

[2] It belongs to a class of compounds known as manganates in which the manganese resides in a +6 oxidation state.

[5] Barium manganate is indefinitely stable, active and can be stored for months in dry conditions.

[7] It does not oxidize saturated hydrocarbons, alkenes, unsaturated ketones, and tertiary amines.

It is easier to prepare, reacts more efficiently, and the substrate:oxidant ratios are closer to theory.

Another use for barium manganate was as a reagent in the synthesis of the inorganic pigment manganese blue, which is no longer produced on an industrial scale.
