Magnesium Sulfate USP Grade Specifications
Sulfuric acid magnesium salt (1:1), hydrate.
Magnesium sulfate (1:1) monohydrate 138.36
Magnesium sulfate (1:1) heptahydrate 246.48 CAS 10034-99-8
Anhydrous 120.37 CAS 7487-88-9

Magnesium Sulfate, rendered anhydrous by ignition, contains not less than 99.0 percent and not more than 100.5 percent of MgSO4.

Identification: A solution (1 in 20) resonds to the tests for Magnesium and for Sulfate.
pH: between 5.0 and 9.2, in a solution (1 in 20).
Loss on drying: Dry it at 105 for 2 hours: the anhydrous form loses not more than 2% of its weight.
Loss on ignition: Weigh accurately about 1 g in a crucible, heat at 105 for 2 hours, then ignite in a muffle furnace at 450 ± 25 to constant weight: the monohydrate loses between 13.0% and 16.0% of its weight, the dried form loses between 22.0% and 28.0% of its weight, and the heptahydrate loses between 40.0% and 52.0% of its weight.
Chloride: A 1.0-g portion shows no more chloride than corresponds to 0.20 mL of 0.020 N hydrochloric acid (0.014%).
Dissolve 0.50 g in 40 mL of water and proceed as directed in the test for Iron: the limit is 20 µg per g.
Heavy metals: Dissolve 2 g in 25 mL of water: the limit is 0.001%.
Selenium: The limit is 0.003%.

Magnesium Sulfate occurs as a colorless crystal or a granular crystalline powder. It is produced with one or seven molecules of water of hydration or in a dried form containing the equivalent of about 2.3 waters of hydration. It is readily soluble in water, slowly soluble in glycerin, and sparingly soluble in alcohol.
Function: Nutrient.

Identification: A 1:20 aqueous solution gives positive tests for Magnesium and for Sulfate.
Assay: Not less than 99.5% of MgSO4 after ignition.
Lead: Not more than 4 mg/kg.
Loss on Ignition Monohydrate: Between 13.0% and 16.0%; Heptahydrate: Between 40.0% and 52.0%; Dried: Between 22.0% and 28.0%.
Selenium: Not more than 0.003%.
