Magnesium Citrate USP
C12H10Mg3O14 451.11
1,2,3-Propanetricarboxylic
acid, hydroxy-, magnesium salt (2:3).
Magnesium citrate (3:2) [3344-18-1].
Magnesium Citrate contains not less than 14.5 percent and not more than 16.4 percent of magnesium (Mg), calculated on the dried basis.
Labeling—
Magnesium Citrate that loses not more
than 2.0% of its weight in the test for Loss on drying may be labeled
as Anhydrous Magnesium Citrate.
Identification—
A: A solution (10 mg per
mL)
responds to the tests for Magnesium.
B: A solution (80 mg per
mL)
responds to the tests for Citrate.
pH: between 5.0 and
9.0, in a suspension (50 mg per mL).
Loss on drying— Dry 1
g in a mechanical convection oven at 135 for 16 hours, then to constant
weight: it loses not more than 29% of its weight, except that where it is
labeled as anhydrous, it loses not more than 2.0% of its weight.
Chloride— A 300-mg portion shows no more
chloride than corresponds to 0.20 mL of 0.020 N hydrochloric acid (0.05%).
Sulfate— A 100-mg portion shows no more sulfate
than corresponds to 0.20 mL of 0.020N sulfuric
acid (0.2%).
Arsenic: 3 6g per g.
Heavy metals— Dissolve 0.4 g in 25
mL of water, and proceed as directed for Test
Preparation, except to use glacial acetic acid to adjust the pH: the
limit is 50 6g per g.
Iron— Boil 50 mg with 5 mL of 2 N nitric acid for 1 minute. Cool, dilute
with water to 45 mL, add 2 mL of hydrochloric acid, and mix: the limit is 200 6g per g.
Limit of calcium—the limit is 1.0%, calculated on the dried
basis. (The method is described in Magnesium Carbonate & Magnesium
Citrate Monograph.
Assay— Weigh accurately about 400 mg of
the substance, dissolve in 50 mL of water,
add 20 mL of ammonia–ammonium chloride buffer TS
and 0.1 mL of eriochrome
black TS, and titrate with 0.05 M edetate disodium VS to a blue endpoint. Perform a blank
determination, and make any necessary correction. From the volume of 0.05 M
edetate disodium
consumed, deduct the volume of 0.05 M edetate disodium corresponding to the amount of calcium
in the portion of Magnesium Citrate taken, based on the amount of calcium
found in the test for Limit of calcium. Each mg of calcium (Ca) is
equivalent to 0.25 mL of 0.05 M edetate disodium.
The difference is the volume of 0.05 M edetate disodium consumed by the magnesium. Each
mL of 0.05 M edetate disodium is equivalent to 1.215 mg of magnesium
(Mg).
