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.

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.
