Manganese chloride tetrahydrate Usage And Synthesis

Chemical Properties

Crystalline

Uses

Manganese Chloride Tetrahydrate is an inorganic chemical reagent used in oxidation studies and reactions.

Uses

Manganese chloride tetrahydrate is a useful agent to detect phospholipid vesicles.

Uses

In dyeing (manganese bister); disinfecting; purifying natural gas; linseed oil drier; in electric batteries.

General Description

Manganese(II) chloride tetrahydrate is a hydrated metal chloride.3 Its toxicity in Swiss mice has been assessed. It participates in the preparation of metal(II) complexes of mixed ligands-dimethydithiocarbamic and p-aminobenzoic acids.3

Biochem/physiol Actions

Manganese is an essential and one of the abundant metal in the tissues of mammals. It plays a key role in the physiological process like development, neuronal function, immune regulation, reproduction, and antioxidant defences. It functions as a cofactor and regulates the activity of the enzymes like oxido-reductases, isomerases, transferases, ligases, lyases and hydrolases It is involved in the innate immunity against viruses.

Purification Methods

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.
