Disodium Hydrogen Citrate
C6H6Na2O7-1.5H2O --- 263.1 --- CAS 144-33-2
Action and use: Anticoagulant.

DEFINITION
Sodium Acid Citrate contains not less than 98.0% and not more than 104.0% of C6H6Na2O7-1.5H2O.

CHARACTERISTICS
A white powder.
Freely soluble in water; practically insoluble in ethanol (96%).

IDENTIFICATION
Yields the reactions characteristic of sodium salts and of citrates.

TESTS
Acidity: pH of a 3% w/v solution, 4.9 to 5.2
Arsenic: 0.50 g dissolved in 25 mL of water complies with the limit test for arsenic (2 ppm).
Chloride: Dissolve 1.0 g in 100 mL of water. 15 mL of the resulting solution complies with the limit test for chlorides, (330 ppm).
Oxalate: To pass the test. (150 ppm, calculated as anhydrous oxalic acid).
Sulfate: Dissolve 0.50 g in 57 mL of water and add 3 mL of 2M hydrochloric acid. 15 mL of the resulting solution complies with the limit test for sulfates, (0.12%).

Trisodium citrate anhydrous CAS 68-04-2
Trisodium citrate dihydrate 294.10 CAS 6132-04-3

Sodium Citrate is anhydrous or contains two molecules of water of hydration. It contains not less than 99.0 percent and not more than 100.5 percent of C6H5Na3O7, calculated on the anhydrous basis.

Identification:
A: A solution (1 in 20) responds to the tests for Sodium and for Citrate.
B: Upon ignition, it yields an alkaline residue which effervesces when treated with 3 N hydrochloric acid.
Alkalinity: A solution of 1.0 g in 20 mL of water is alkaline to litmus paper, but after the addition of 0.20 mL of 0.10 N sulfuric acid no pink color is produced by 1 drop of phenolphthalein TS.
Water: Dry it at 180 for 18 hours: the anhydrous form loses not more than 1.0%, and the hydrous form between 10.0% and 13.0%, of its weight.
Tartrate: the limit is 0.001%.

Readily carbonizable substances: To 0.20 g of the powdered substance to be examined add 10 ml of sulphuric acid and heat in a water-bath at 90 ± 1 °C for 60 min. Cool rapidly. The solution is not more intensely coloured than reference solution.
Chlorides: Maximum 50 ppm.
Oxalates: Maximum 300 ppm.
Sulphates: Maximum 150 ppm.
Heavy metals: Maximum 10 ppm.
Water: 11.0 per cent to 13.0 per cent, determined on 0.300 g. After adding the substance to be examined, stir for 15 min before titrating.
