Manganese Sulfate

CAS 7785-87-7 · Formula MnO4S · MW 151.00 g/mol

The principal water-soluble manganese feedstock, supplying the metal for electrolytic processing while also serving agriculture and ceramics. It is used as a manganese micronutrient in fertilizers and animal feeds, as the precursor for electrolytic manganese metal and manganese dioxide, as a catalyst and paint drier, as a ceramic glaze colorant, and as a mordant in textile dyeing.

Frequently Asked Questions

What is manganese sulfate used for?

Manganese sulfate (CAS 7785-87-7) is a water-soluble manganese salt used as a manganese micronutrient in fertilizers and animal feeds, as the precursor for electrolytic manganese metal and manganese dioxide, as a catalyst and drier in varnishes and oxidation processes, as a ceramic-glaze colorant, and as a mordant in textile dyeing.

Is manganese sulfate the same as magnesium sulfate?

No. Manganese sulfate (MnSO4, CAS 7785-87-7) contains the trace metal manganese, while magnesium sulfate (MgSO4) contains magnesium — different elements with different CAS numbers and uses. They are not interchangeable; confirm which one you need when ordering.

Is Epsom salt manganese sulfate?

No. Epsom salt is magnesium sulfate heptahydrate (MgSO4·7H2O). Manganese sulfate (MnSO4) is a separate manganese salt used as a micronutrient and chemical precursor. The names are sometimes confused because both are sulfate salts, but they are chemically distinct.

Is manganese sulfate water soluble, and which hydrate is supplied?

Manganese sulfate is freely water soluble, which suits its use as a soluble micronutrient and dye mordant. It is commonly traded as the monohydrate (MnSO4·H2O); specify the hydration form and grade (e.g. fertilizer/feed) you require when requesting a quote.

What is the cost of bulk manganese sulfate?

Bulk manganese sulfate pricing depends on volume, grade, hydration form, and delivery point. RawSource supplies it by the bag, drum, tote, or truckload — request a bulk quote and we will return current pricing with a CoA and SDS.
