Manganese II Chloride Tetrahydrate Extrapure 97% 500g SRL

Manganese(II) chloride tetrahydrate is a pale pink to pink crystalline powder, a salt form of manganese, with the chemical formula MnCl24H2O. It's an excellent water-soluble source of manganese, particularly useful in applications where chlorides are needed. The "extrapure" grade indicates a higher purity than standard laboratory-grade reagents. Here's a more detailed look:Key Features:

• Appearance: Pale pink to pink crystalline powder. 
• Purity: "Extrapure" grade signifies a higher purity, often with minimal trace impurities like iron, calcium, copper, and lead. 
• Solubility: Highly soluble in water (99 g/l at 20C). 
• Applications: Used in dry cell battery production, as a precursor in organic chemistry, and in certain biochemical applications like DNA tailing and reverse transcription. 

Physical Properties:

• Molecular Weight: 197.90 g/mol.
• Melting Point: 58C.
• Boiling Point: 198C.
• Density: 2.01 g/cm3. 

Specifications (typical for extrapure grade):

• Assay: Min 97%.
• Trace impurities: Max 0.005% Iron (Fe), max 0.025% Potassium (K), max 0.05% Sodium (Na), etc.
• pH: 4-6. 

Safety:Harmful if swallowed, Avoid contact with skin and eyes, Wash thoroughly with water in case of contact, and Store in a dry place. In summary, Manganese(II) chloride tetrahydrate extrapure is a high-purity, water-soluble compound used in various industrial and research applications. Its pink color and crystalline form are characteristic, and it's important to handle it with caution due to its potential for harm if swallowed or in contact with skin/eyes.
