Calcium Phosphate Dibasic or Dicalcium Phosphate Dihydrate CAS Number 7757-93-9, 65-85-0 and 7789-77-7, EINECS EC Number 231-826-1, HS Code: 283525**, Molecular Weight 172.1, Chemical Formula CaHPO4-2H2O

Dibasic Calcium Phosphate BP Ph Eur

DEFINITION
Content: Dibasic Calcium Phosphate 98.0 per cent to 105.0 per cent.

CHARACTERS
Appearance: White, crystalline powder.
Solubility: Practically insoluble in cold water and in alcohol. It dissolves in dilute hydrochloric acid and in dilute nitric acid.

IDENTIFICATION
A. Dissolve 0.1 g in a mixture of 5 ml of dilute nitric acid and 5 ml of water. The solution gives reaction of phosphates.
B. 5 mg gives reaction of calcium.
C. It complies with the limits of the assay.

TESTS
Solution S: Dissolve 2.5 g in 20 ml of dilute hydrochloric acid, filter if necessary and add dilute ammonia until a precipitate is formed. Add just sufficient dilute ydrochloric acid to dissolve the precipitate and dilute to 50 ml with distilled water.
Carbonates: Shake 0.5 g with 5 ml of carbon dioxide-free water and add 1 ml of hydrochloric acid. No effervescence is produced.
Chlorides: Maximum 330 ppm.
Dissolve 0.5 g in a mixture of 1 ml of nitric acid and 10 ml of water and dilute to 50 ml with water. 15 ml of the solution complies with the limit test for chlorides.
Fluorides: Maximum 100 ppm.
Sulphates: Maximum 0.5 per cent.
Arsenic: Maximum 10 ppm.
Barium: To 10 ml of solution S add 0.5 ml of dilute sulphuric acid. After 15 min, any opalescence in the solution is not more intense than that in a mixture of 10 ml of solution S and 0.5 ml of distilled water.
Iron: Maximum 400 ppm.
Heavy metals: Maximum 40 ppm.
1 ml of 0.1 M sodium edetate is equivalent to 17.21 mg of CaHPO4,2H2O.

Phosphoric acid, calcium salt (1:1).
Calcium phosphate (1:1) CAS 7757-93-9
Dihydrate 172.09 CAS 7789-77-7

Dibasic Calcium Phosphate is anhydrous or contains two molecules of water of hydration. It contains not less than 98.0 percent and not more than 105.0 percent of anhydrous dibasic calcium phosphate (CaHPO4) or of dibasic calcium phosphate dihydrate (CaHPO4·2H2O).

Identification:
A: Dissolve about 100 mg by warming with a mixture of 5 mL of 3 N hydrochloric acid and 5 mL of water, add 2.5 mL of 6 N ammonium hydroxide drop wise, with shaking, and then add 5 mL of ammonium oxalate TS: a white precipitate is formed.
B: To 10 mL of a warm solution (1 in 100) in a slight excess of nitric acid add 10 mL of ammonium molybdate TS: a yellow precipitate of ammonium phosphomolybdate is formed.
Loss on ignition: Ignite it at 800 to 825 to constant weight: anhydrous Dibasic Calcium Phosphate loses between 6.6% and 8.5% of its weight, and the dihydrate form of Dibasic Calcium Phosphate loses between 24.5% and 26.5% of its weight.
Carbonate: Mix 1.0 g with 5 mL of water, and add 2 mL of hydrochloric acid: no effervescence occurs.
Chloride: To 0.30 g add 10 mL of water and 2 mL of nitric acid, and warm gently, if necessary, until no more dissolves. Dilute to 25 mL, filter, if necessary, and add 1 mL of silver nitrate. TS: the turbidity does not exceed that produced by 1.0 mL of 0.020 N hydrochloric acid (0.25%).
Sulfate: Dissolve 1.0 g in the smallest possible amount of 3 N hydrochloric acid, dilute with water to 100 mL, and filter, if necessary. To 20 mL of the filtrate add 1 mL of barium chloride. TS: the turbidity does not exceed that produced by 1.0 mL of 0.020 N sulfuric acid (0.5%).
Arsenic:The limit is 3 µg per g.
Barium: Heat 0.50 g with 10 mL of water, and add hydrochloric acid drop wise, stirring after each addition, until no more dissolves. Filter, and to the filtrate add 2 mL of potassium sulfate TS: no turbidity is produced within 10 minutes.
Heavy metals: the limit is 0.003%.
Limit of acid-insoluble substances: not more than 0.2% of acid-insoluble substances is found.
Limit of fluoride: [NOTE—Prepare and store all solutions in plastic containers.]: the limit is 0.005%.

DESCRIPTION
Calcium Phosphate, Dibasic, occurs as a white powder. It is anhydrous or contains two molecules of water of hydration. It is stable in air. It is insoluble in alcohol, is practically insoluble in water, but is readily soluble in dilute hydrochloric and nitric acids.
Function: Leavening agent; dough conditioner; nutrient; yeast food.

REQUIREMENTS
> Labeling: Indicate whether it is anhydrous or the dihydrate.
Identification:
A. Dissolve about 100 mg of sample by warming it with a mixture of 5 mL of 2.7 N hydrochloric acid and 5 mL of water. Add 2.5 mL of 6 N ammonium hydroxide, drop-wise, with shaking, and then add 5 mL of ammonium oxalate TS. A white precipitate forms.
B. Add 10 mL of ammonium molybdate TS to 10 mL of a warm 1:100 aqueous solution in a slight excess of nitric acid. A yellow precipitate of ammonium phosphomolybdate forms.
Assay Anhydrous or Dihydrate: Not less than 97.0% and not more than 105.0% Dibasic Calcium Phosphate.
Arsenic: Not more than 3 mg/kg.
Fluoride: Not more than 0.005%.
Lead: Not more than 2 mg/kg.
Loss on Ignition Anhydrous: Between 7.0% and 8.5%; Dihydrate: Between 24.5% and 26.5%.
