Magnesium Citrate USP Grade Specifications
C12H10Mg3O14 451.11
1,2,3-Propanetricarboxylic acid, hydroxy-, magnesium salt (2:3).
Magnesium citrate (3:2) CAS 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).
