C10H14N2Na2O8-2H2O --- 372.24
Glycine, N,N′-1,2-ethanediylbis[N-(carboxymethyl)-, disodium salt, dihydrate.
Disodium (ethylenedinitrilo)tetraacetate dihydrate CAS 6381-92-6
Anhydrous 336.21 CAS 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 and 2 drops of ferric chloride, 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: no precipitate is formed.
Heavy metals: 0.005%.
Limit of nitrilotriacetic acid: not more than 0.1% of nitrilotriacetic acid is found.

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.
