Chemistry & industry
Applications
UsesManganese(II) chloride is used in dyeing and printing textiles and as a disinfectant. It also is used in dry cell batteries; for the preparation of drying agents for paints and varnishes; as a catalyst in chlorination reactions; in the production of several manganese salts, including methylcyclopentadienylmanganese tricarbonyl used as a colorant for brick. In metallurgy, the compound is used as an alloying agent and is added to molten magnesium to produce magnesium-manganese alloys.
DescriptionManganese, an essential nutrient, occurs in many foods of plant and animal origin. The naturally occurring manganese levels vary from about 2 0 ppm in nuts, cereals, dried fruits and non-leafy vegetables to less than 1 ppm in animal products. Manganous chloride tetrahydrate is pink translucent crystals which are very soluble in water.1 .
UsesManganese chloride (MnCl2) is used in the pharmaceutical industry as a dietary supplement and is added to fertilizers.
UsesA novel high-spin hexanuclear Mn(III) cluster, [NaMn6(OMe)12(dbm)6]+, was synthesized via MnCl2 oxidation with simultaneous NaOMe promoted aggregation. This cluster has an unprecedented cyclic structure and 24 unpaired electrons in its ground state.1 Also used in the formation of an active Mn(0) species useful for radical cyclization reactions.2
UsesUsed mainly in the production of dry cell batteries
UsesManganese Chloride is a source of manganese that functions as a nutrient and dietary supplement. it exists as crystals which are readily soluble in room temperature (22°c) water and are very soluble in hot water. see manganese.
General DescriptionManganese (II) chloride (MnCl2) might play a key role in integrin activation. Manganese is indispensable for brain function and is an essential cofactor for several key enzymes like superoxide dismutase and enzymes involved in neurotransmitter synthesis. Manganese can modulate iron and calcium homeostasis. Manganese is also used in the magnetic resonance imaging to increase contrast while examining neuronal connections and brain cytoarchitecture. High levels of manganese is toxic to central nervous system and causes Parkinson′s like symptoms called as manganism. MnCl2 has been used in reverse transcription reaction mix to enhance the template-switching efficiency.
