Synonyms: ----
CAS Number: 3344-18-1, Molecular Weight: 451.11, Chemical Formula: C12H10Mg3-O14, EINECS EC Number: ----, FEMA: ----,

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.


Anhydrous Magnesium Citrate BP Grade

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.
