Manganese dioxide - Wikipedia

Manganese dioxide is the inorganic compound with the formula MnO 2. This blackish or brown solid occurs naturally as the mineral pyrolusite, which is the main ore of manganese and a component of manganese nodules. The principal use for MnO 2 is for dry-cell batteries, such as the alkaline battery and the zinc–carbon battery. MnO 2 is also used as a pigment and as a precursor to other manganese compounds, such as KMnO 4. It is used as a reagent in organic synthesis, for example, for the oxidation of

Manganese Dioxide - an overview ScienceDirect Topics

Manganese dioxide is a mild and selective oxidant used for this purpose, although the reaction conditions may be critical to prevent over-oxidation. For example, short exposure of pyridoxol to activated manganese dioxide under acidic conditions affords pyridoxal in good yield whilst 4-pyridoxic acid is formed under basic conditions (Scheme 7) .
