Beschreibung
Manganese, 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
.
Chemische Eigenschaften
MnCl2 is rose-colored deliquescent crystals that are very soluble in water,and melts at 650°C and boils at 1190°C. The tetrahedral form, MnCI2.4H20 , melts at 58°C and loses its water at 198°C and is used as a catalyst in paints,dyes,pharmaceuticals, and fertilizers, and for various other purposes.
Verwenden
Manganese 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.
Allgemeine Beschreibung
Manganese (II) chloride (MnCl
2) 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. MnCl
2 has been used in reverse transcription reaction mix to enhance the template-switching efficiency.
Sicherheitsprofil
Poison by
intraperitoneal, subcutaneous, intramuscular,
intravenous, and parenteral routes.
Moderately toxic by ingestion. Experimental
teratogenic and reproductive effects.
Questionable carcinogen with experimental
carcinogenic data. Mutation data reported.
Explosive reaction when heated with zinc
foil. Reacts violently with potassium or
sodium. When heated to decomposition it
emits toxic fumes of Cl-. See also
MANGANESE COMPOUNDS and
CHLORIDES.
l?uterung methode
It crystallises from water (0.3mL/g) on cooling. The red-rose tetrahydrate melts at ~52o and forms the dihydrate salt which loses all its H2O at 198o to give MnCl2. It is soluble in EtOH.
