Hydrated Manganese Glycerophosphate BP Ph Eur Grade Specifications
C3H7MnO6P-xH2O -- 225.0
DEFINITION
Mixture of variable proportions of hydrated manganese (II) (2RS)-2,3-dihydroxypropyl phosphate and hydrated manganese (II) 2-hydroxy-1-(hydroxymethyl)ethyl phosphate.
Content: 97.0 per cent to 102.0 per cent (dried substance).
CHARACTERS
Appearance: White or pale pink, hygroscopic powder.
Solubility: Practically insoluble in water and in ethanol (96 per cent). It is freely soluble in dilute mineral acids.
IDENTIFICATION
A. Mix 1 g with 1 g of potassium hydrogen sulphate R in a test tube fitted with a delivery 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 R. The filter paper develops a blue colour in contact with piperidine.
B. Disperse 50 mg in 5 ml of water R. Add 0.5 ml of ammonium sulphide solution. A pale pink precipitate is formed that dissolves on the addition of 1 ml of acetic acid R.
C. Ignite 0.1 g in a crucible. Take up the residue with 5 ml of nitric acid R and heat on a water-bath for 1 min. Filter. The filtrate gives reaction (b) of phosphates.
TESTS
Solution S: Dissolve 5.0 g in 20 ml of dilute hydrochloric acid. Filter if necessary. Add dilute ammonia until a precipitate is formed. Dissolve the precipitate by adding the minimum quantity needed of dilute hydrochloric acid and dilute to 100 ml with distilled water.
Glycerol and ethanol (96 per cent)-soluble substances: Maximum 1.0 per cent.
Shake 1.00 g with 25 ml of ethanol (96 per cent) for 1 min. Filter. Evaporate the filtrate to dryness on a water-bath and dry the residue at 70C for 1 h. The residue weighs a maximum of 10 mg.
Chlorides: Maximum 0.15 per cent.
Phosphates: Maximum 0.3 per cent.
Sulphates: Maximum 0.2 per cent.
Iron: Maximum 50 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 105C for 4 h.
