Product Description

Magnesium Acetate Tetrahydrate


Molecular Formula: (C2H3O2)2Mg.4H2O
Molecular Weight : 214.46 (Tetrahydrate)
CAS: [16674-78-5]


DESCRIPTION
Magnesium acetate appears as white hygroscopic crystals. It smells like acetic acid and is soluble in water. When it is in an aqueous solution its pH will be on the alkaline side of neutral.

EINECS: 205-554-9
Molecular formula: C4H14MgO8

OTHER NAME

Magnesium acetate,anhydrous; Acetic acid magnesium salt; Magnesium di(acetate); Magnesium acetate; Acetic acid, magnesium salt (2:1); Acetic acid, magnesium salt; acetate, magnesium salt (1:1); acetate, magnesium salt, hydrate (1:1:4);

Applications
Magnesium acetate is commonly used as a source of magnesium or for the acetate ion in chemistry experiments. One example of this is when magnesium acetate and magnesium nitrate were both used to perform molecular dynamics simulations and surface tension measurements. In the experiment the authors found that the acetate had a stronger affinity for the surface compared to the nitrate ion and that the Mg2+ strongly repelled away from the air/liquid interference. They also found that the Mg2+ had a stronger tendency to bind with the acetate ion compared to the nitrate.

One of the more prevalent uses of magnesium acetate is in the mixture called calcium magnesium acetate (CMA). It is a mixture of calcium acetate and magnesium acetate. CMA is thought of as an environmentally friendly alternative deicer to NaCl and CaCl2. CMA also acts as a powerful SO2, NOx, and toxic particulate emission control agent in coal combustion processes to reduce acid rain, and as an effective catalyst for the facilitation of coal combustion.

Magnesium acetate has been found to cause a conformational change in Escherichia coli enzyme Primase. In this experiment Mg(OAc)2, MnCl2, CaCl2, NaOAc, LiCl, MgSO4 and MgCl2 were all compared to see what effect they had on the Escherichia coli enzyme Primase. The experimenters found that Mg(OAc)2 caused the best conformational change. MgSO4 and MgCl2 induced the effect slightly while the rest did not.

When magnesium acetate is mixed with hydrogen peroxide it acts as a bactericidal.

Magnesium acetate has been shown to be effective at ashing organic compounds in preparation for a fluorine analysis when high or low concentrations of fluorine are present.

Chlorides: Maximum 330 ppm.
Nitrates: Maximum 3 ppm.
Sulphates: Maximum 600 ppm.
Aluminium: Maximum 1 ppm.
Calcium: Maximum 100 ppm.
Potassium: Maximum 0.1 per cent.
Sodium: Maximum 0.5 per cent.
Heavy metals: Maximum 40 ppm.
Readily oxidizable substances: Dissolve 2.0 g in 100 ml of boiling water, add 6 ml of a 150 g/l solution of sulphuric acid and 0.3 ml of 0.02 M potassium permanganate. Mix and boil gently for 5 min. The pink colour is not completely discharged.
Water: 33.0 per cent to 35.0 per cent, determined on 0.100 g.
