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.cnki翻译助手
Packaging and storage— Prerve in tight containers.
Labeling— Magnesium Citrate that los 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 191.
B: A solution (80 mg per mL) responds to the tests for Citrate 191. ssou
pH 791: between 5.0 and 9.0, in a suspension (50 mg per mL).
Loss on drying 731— Dry 1 g in a mechanical convection oven at 135 for 16 hours, then to constant weight: it los not more than 29% of its weight, except that where it is labeled as anhydrous, it los not more than 2.0% of its weight.
Chloride 221— A 300-mg portion shows no more chloride than corresponds to 0.20 mL of 0.020 N hydrochloric acid (0.05%).
Sulfate 221— A 100-mg portion shows no more sulfate than corresponds to 0.20 mL of 0.020 N sulfuric acid (0.2%).
