Edetate Calcium Disodium USP NF Grade Specifications
C10H12CaN2Na2O8.xH2O (anhydrous) --- 374.27
Calciate(2-), [[N,N′-1,2-ethanediylbis[N-(carboxymethyl)glycinato]](4-)-N,N′,O,O′,ON,ON′]-, disodium, hydrate, (OC-6-21)-. Disodium[(ethylenedinitrilo)tetraacetato]calciate(2-)hydrate CAS 23411-34-9 and Anhydrous CAS 62-33-9]
Edetate Calcium Disodium is a mixture of the dihydrate and trihydrate of calcium disodium ethylenediaminetetraacetate (predominantly the dihydrate). It contains not less than 97.0 percent and not more than 102.0 percent of C10H12CaN2Na2O8, calculated on the anhydrous basis.
Identification:
A: Infrared Absorption.
B: A solution (1 in 20) responds to the oxalate test for Calcium and to the flame test for Sodium.
C: To 5 mL of water add 2 drops of ammonium thiocyanate and 2 drops of ferric chloride. To the deep red solution add about 50 mg of Edetate Calcium Disodium, and mix: the deep red color disappears.
pH: between 6.5 and 8.0, in a solution (1 in 5).
Water: not more than 13.0%.
Heavy metals: 0.002%.
Limit of nitrilotriacetic acid: To pass the test (0.1%).
Magnesium-chelating substances: Weigh accurately 1.0 g, transfer to a small beaker, and dissolve in 5 mL of water. Add 5 mL of ammonia-ammonium chloride buffer. Then to the buffered solution add 5 drops of eriochrome black, and titrate with 0.10 M magnesium acetate to the appearance of a deep wine-red color: not more than 2.0 mL is required.

DESCRIPTION
Calcium Disodium EDTA occurs as white, crystalline granules or as a white to off white powder. It is slightly hygroscopic and is stable in air. It is freely soluble in water.
Function: Preservative; sequestrant.
Identification:
A. A 1:20 aqueous solution responds to the oxalate test for Calcium and to the flame test for Sodium.
B. The infrared absorption spectrum of a mineral oil dispersion of sample exhibits maxima only at the same wavelengths as those of a similar preparation of USP Edetate Calcium Disodium Reference Standard.
C. Add 2 drops of ammonium thiocyanate and 2 drops of ferric chloride to 5 mL of water contained in a test tube. Add about 50 mg of sample to the deep red solution so obtained, and mix. The deep red color disappears.
Assay: Not less than 97.0% and not more than 102.0% of C10H12CaN2Na2O8, calculated on the anhydrous basis.
Lead: Not more than 4 mg/kg.
Magnesium-Chelating Substances: Passes test.
Nitrilotriacetic Acid: Not more than 0.1%.
pH of a 1:100 Solution: Between 6.5 and 7.5.
Water: Not more than 13.0%.
