Magnesium Glycerophosphate BP Ph Eur Grade Specifications
C3H7MgO6P -- 194.4 -- CAS 927-20-8
Mixture, in variable proportions, of magnesium salts of (RS)-2,3-dihydroxypropyl phosphate and 2-hydroxy-1-(hydroxymethyl)ethyl phosphate, which may be hydrated.
Content: 11.0 per cent to 12.5 per cent of Mg (dried substance).
Appearance: White or almost white powder, hygroscopic.
Solubility: Practically insoluble in ethanol (96 per cent). It dissolves in dilute solutions of acids.
A. Mix 1 g with 1 g of potassium hydrogen sulphate in a test tube fitted with a glass tube. Heat strongly and direct the white vapour towards a piece of filter paper impregnated with a freshly prepared 10 g/l solution of sodium nitroprusside. The filter paper develops a blue colour in contact with piperidine.
B. Ignite 0.1 g in a crucible. Take up the residue with 5 ml of nitric acid and heat on a water-bath for 1 min. Filter. The filtrate gives reaction (b) of phosphates.
C. It gives the reaction of magnesium.
Solution S: Dissolve 2.5 g in carbon dioxide-free water prepared from distilled water and dilute to 50 ml with the same solvent.
Appearance of solution: Solution S is not more opalescent than reference suspension.
Acidity: Dissolve 1.0 g in 100 ml of carbon dioxide-free water. Add 0.1 ml of phph solution. Not more than 1.5 ml of 0.1 M sodium hydroxide is required to change the colour of the indicator.
Glycerol and ethanol (96 per cent)-soluble substances: Maximum 1.5 per cent.
Shake 1.0 g with 25 ml of ethanol (96 per cent) for 2 min. Filter and wash the residue with 5 ml of ethanol (96 per cent). Combine the filtrate and the washings, evaporate to dryness on a water-bath and dry the residue at 70C for 1 h. The residue weighs a maximum of 15 mg.
Chlorides: Maximum 0.15 per cent.
Phosphates: Maximum 0.5 per cent.
Sulphates: Maximum 0.1 per cent.
Iron: Maximum 150 ppm.
Heavy metals: Maximum 20 ppm.
Loss on drying: Maximum 12.0 per cent, determined on 1.000 g by drying in an oven at 150C for 4 h.
