Anhydrous Magnesium Citrate BP Grade
Mg3(C6H5O7)2 --- 451.1 --- 3344-18-1
Ph Eur

DEFINITION
Trimagnesium bis(2-hydroxypropane-1,2,3-tricarboxylate).
Content: 15.0 per cent to 16.5 per cent of Mg (dried substance).

CHARACTERS
Appearance: White or almost white, fine, slightly hygroscopic powder.
Solubility: Soluble in water, practically insoluble in ethanol (96 per cent). It dissolves in dilute  hydrochloric acid.

IDENTIFICATION
A. It gives the reaction of citrates.
B. It gives the reaction of magnesium.
C. pH (see Tests).
D. Loss on drying (see Tests).

TESTS
Solution S: Dissolve 5.0 g in carbon dioxide-free water R, heating at 60C, cool and dilute to 100  mL with the same solvent.
Appearance of solution: Solution S is not more opalescent than reference suspension and not more  intensely coloured than reference solutions.
