Sodium Acetate USP Grade Specifications
Sodium Acetate USP
C2H3NaO2-3H2O -- 136.08
Assay: Sodium Acetate contains three molecules of water of hydration, or is anhydrous. It contains not less than 99.0 percent and not more than 101.0 percent of C2H3NaO2, calculated on the dried basis.
Labeling: Label it to indicate whether it is the trihydrate or is anhydrous. Where Sodium Acetate is intended for use in hem dialysis, it is so labeled.
Identification: A solution responds to the test for Sodium and for Acetate.
pH: between 7.5 and 9.2, in a solution in carbon dioxide-free water containing the equivalent of 30 mg of anhydrous sodium acetate per mL.
Loss on drying: Dry at 120 to constant weight: the hydrous form loses between 38.0% and 41.0% of its weight, and the anhydrous form loses not more than 1.0% of its weight.
Insoluble matter: Dissolve the equivalent of 20 g of anhydrous sodium acetate in 150 mL of water, heat to boiling, and digest in a covered beaker on a steam bath for 1 hour. Filter through a tarred filtering crucible, wash thoroughly, and dry at 105 : the weight of the residue does not exceed 10 mg (0.05%).
Chloride: A portion equivalent to 1.0 g of anhydrous sodium acetate shows no more chloride than corresponds to 0.50 mL of 0.020 N hydrochloric acid (0.035%).
Sulfate: A portion equivalent to 10 g of anhydrous sodium acetate shows no more sulfate than corresponds to 0.50 mL of 0.020 N sulfuric acid (0.005%).
Calcium and magnesium: To 20 mL of a solution containing the equivalent of 10 mg of anhydrous sodium acetate per mL add 2 mL each of 6 N ammonium hydroxide, ammonium oxalate, and dibasic sodium phosphate TS: no turbidity is produced within 5 minutes.
Potassium— Dissolve the equivalent of 3 g of anhydrous sodium acetate in 5 mL of water, add 1N acetic acid drop wise until the solution is slightly acidic, and then add 5 drops of sodium cobalt nitrite TS: no precipitate is formed.
Aluminum: (where it is labeled as intended for use in hem dialysis)— the limit is 0.2µ =g per g.
Heavy metals: the limit is 0.001%.
Organic volatile impurities: meets the requirements.
Sodium Acetate FCC Food Grade Specifications
C2H3NaO2 Formula weight, anhydrous 82.03
C2H3NaO2-3H2O Formula weight, trihydrate 136.08
Sodium Acetate occurs as colorless, transparent crystals or as a granular, crystalline or white powder. The anhydrous form is hygroscopic; the trihydrate effloresces in warm, dry air. One gram of the anhydrous form dissolves in about 2 mL of water; 1 g of the trihydrate dissolves in about 0.8 mL of water and in about 19 mL of alcohol.
Identification: A 1:20 aqueous solution gives positive tests for Sodium and for Acetate.
Assay: Not less than 99.0% and not more than 101.0% of C2H3NaO2 after drying.
Alkalinity Anhydrous: Not more than 0.2%; Trihydrate: Not more than 0.05%.
Lead: Not more than 2 mg/kg.
Loss on Drying: Anhydrous: Not more than 1.0%; Trihydrate: Between 36.0% and 41.0%.
Potassium Compounds: Passes test.
