説明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 .

使用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.

一般的な説明Manganese (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.

使用用途塩化マンガン(II)は幅広く使用されています。主な用途は、染色工業、窯業用顔料、医薬品製造、塩化物合成の触媒です。また、塗料乾燥剤 (褐色ピグメント) や塗料乾燥剤のホウ酸マンガンの製造にも使用可能です。 化学肥料の合成促進剤、印刷インキの乾燥剤、乾電池の原料、軽合金用フラックス、、にも用いられています。医療でも、核磁気共鳴画像法 (MRI) 用造影剤や無機質性剤として使用されています。
