Solubility
Soluble in water, practically insoluble in ethanol (96 per cent).
IDENTIFICATION
First identification A,
B, D.
Second identification B,
C, D.
A. Infrared absorption
spectrophotometry.
B. Dissolve 2 g in 25 ml of
water, add 6 ml of lead nitrate solution, shake and add 3 ml
of potassium iodide solution. No yellow precipitate is formed.
Make alkaline to red litmus paper by the addition of dilute
ammonia. Add 3 ml of ammonium oxalate solution R. No precipitate is
formed.
C. Dissolve 0.5 g in 10 ml of
water and add 0.5 ml of calcium chloride solution. Make
alkaline to red litmus paper by the addition of dilute ammonia
and add 3 ml of ammonium oxalate solution. No precipitate is formed.
D. It gives the reactions of
sodium.
Solution S
Dissolve 5.0 g in carbon dioxide-free water and dilute to 100 ml with the same solvent.
Appearance of solution
Solution S is clear and colourless.
pH
4.0 to 5.5 for solution S.
Impurity A
Liquid chromatography. Carry out the test protected from light.
To pass the test
Limit:—impurity A: not more than the area of the corresponding peak in the chromatogram obtained with the reference solution (0.1 per cent).

Disodium (ethylenedinitrilo)tetraacetate dihydrate [6381-92-6].
Anhydrous 336.21 [139-33-3].
Edetate Disodium contains not less than 99.0 percent and not more than 101.0 percent of C10H14N2Na2O8, calculated on the dried basis.
Identification—
A:
Infrared Absorption 197K : un-dried.
B: To 5
mL of water in a test tube
add 2 drops of ammonium thiocyanate TS and 2 drops of ferric chloride TS, and mix. To the
deep red solution add about 50 mg of Edetate
Disodium, and mix: the red color is discharged, leaving a yellowish
solution.
C: It responds to the flame test for Sodium.
pH: between 4.0
and 6.0, in a solution (1 in 20).
Loss on drying— Dry it at 150 for 6 hours: it loses not less than
8.7% and not more than 11.4% of its weight.
Calcium— To a solution (1 in 20) add 2 drops of methyl red TS,
and neutralize with 6 N ammonium hydroxide. Add 3 N hydrochloric acid
drop-wise until the solution is just acid,
and then add 1 mL of ammonium oxalate TS: no
precipitate is formed.
Heavy metals:
0.005%.
Limit of nitrilotriacetic acid— not more than 0.1% of nitrilotriacetic
acid is found.

INS: 386 CAS: [6381-92-6]
DESCRIPTION
EDTA Disodium occurs as a white, crystalline powder. It is soluble
in water.
REQUIREMENTS
Identification
A. A 1:20 aqueous solution responds to the flame test for Sodium.
B. Add 2 drops of ammonium
thiocyanate TS
and 2 drops of ferric chloride TS to 5 mL of
water in a test tube. Add about 50 mg of sample to the deep red solution
so obtained, and mix. The deep red color disappears.
C. The infrared absorption spectrum of a potassium bromide dispersion of
sample exhibits relative maxima at the same wavelengths as those of a
similar preparation of USP Edetate Disodium
Reference Standard.
Assay: Not less than 99.0% and not more than
101.0% of C10H14N2Na2O8·2H2O.
Calcium: Negative.
Lead: Not more than 10 mg/kg.
Nitrilotriacetic Acid: Not more
than 0.1%.
pH of a 1:100 Solution: Between
4.3 and 4.7.
