C10H16N2O8
-- 292.2 -- 60-00-4
Edetic Acid EDTA
Action and use
Chelating agent; pharmaceutical aid.
DEFINITION
(Ethylenedinitrilo)tetraacetic acid.
Content
98.0 per cent to 101.0 per cent. (EDTA)
CHARACTERS
Appearance
White or almost white, crystalline powder or colourless crystals.
Solubility
Practically insoluble in water and in ethanol (96 per cent). It
dissolves in dilute solutions of alkali hydroxides.
IDENTIFICATION
First identification: A.
Second identification: B, C.
A. Infrared absorption spectrophotometry as per prescribed
method.
B. To 5 ml of
water add 0.1 ml of ammonium thiocyanate
solution and 0.1 ml of ferric chloride solution and mix. The
solution is red. Add 0.5 ml of solution S (see Tests). The solution becomes
yellowish.
C. To 10 ml of solution S 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.
TESTS
Solution S
Dissolve 5.0 g in 20 ml of dilute sodium hydroxide solution
and
dilute to 100 ml with water.
Appearance of solution
Solution S is clear and colourless.
Impurity A
Liquid chromatography.
Carry out the test protected from light.
As per Monograph
—impurity A: not more than the area of the corresponding peak in the
chromatogram obtained with the reference solution (0.1 per cent).
Chlorides
Maximum 200 ppm.
Iron
Maximum 80 ppm.
Heavy metals
Maximum 20 ppm.
Sulphated ash
Maximum 0.2 per cent, determined on 1.0 g.

(Ethylenedinitrilo)tetraacetic acid [60-00-4].
Edetic Acid contains not less than 98.0 percent and not more than 100.5 percent of C10H16N2O8.
Identification: Infrared Absorption
197K.
Residue on ignition:
not more than 0.2%.
Heavy metals: 0.003%.
Iron— Char 3.0 g thoroughly, and heat in an oven at 500 until most of
the carbon is consumed. Cool, add 0.15 mL of nitric acid, and heat at 500
until all of the carbon is consumed. Dissolve the residue in 2 mL of a
mixture of equal volumes of hydrochloric acid and water, digest in a covered
dish on a steam bath for 10 minutes, remove the cover, and evaporate to
dryness. Dissolve the residue in 1 mL of 1 N acetic acid and 20 mL of hot
water, digest for 5 minutes on a steam bath, cool, and dilute with water to
30 mL. To 2.0 mL of this solution add 2 mL of hydrochloric acid, and dilute
with water to 50 mL. Add about 50 mg of ammonium persulfate and 3 mL of
ammonium thiocyanate solution (3 in 10), mix, and transfer to a
color-comparison tube. Treat in the same manner 2.0 mL of a solution of
ferric ammonium sulfate, prepared by dissolving 43.2 mg of ferric ammonium
sulfate in 10 mL of 2 N sulfuric acid and adding water to make 1000 mL, each
mL representing 5 :g of Fe. The color of the test solution is not deeper
than that of the solution containing the standard iron solution (0.005%).
