Uses
Different sources of media describe the Uses of 62-33-9 differently. You can refer to the following data:
1. Chelating agent (metal).
2. EDTA calcium disodium is a sequestrant and chelating agent whose complete name is disodium calcium ethylenediamine tetraacetate. It is a nonhygroscopic powder that is colorless, odorless, and tasteless at recommended use levels. A 1% solution has a ph of 6.5–7.5. It is used to control the reaction of trace metals with some organic and inorganic components in food; to prevent deterioration of color, texture, and development of precipitates; and to prevent oxidation. Its function is comparable to that of disodium dihydrogen edta. It is also termed calcium disodium edta.
3. Used to eliminate enzyme inhibition by traces of heavy metals, and to inhibit enzymes that require divalent cations as cofactors. As this form is already chelated with Ca2+, it is selective for divalent cations with greater affinity for EDTA, which it will exchange for Ca2+.
Brand name
Calcium Disodium Versenate (3M Pharmaceuticals).
Pharmaceutical Applications
Calcium disodium edetate, also referred to as calcium sodium EDTA, stands for the chemical compound 2,2 ,2 ,2 -(ethane-1,2-diyldinitrilo)tetraacetic acid, which is a synthetic amino acid. Edetate refers to the calcium disodium salt of the chelating agent with the formula (HO2CCH2)2NCH2CH2N(CH2CO2H)2. In the United States, it is found under the name calcium disodium versenate. Edetate is mainly used to complex di and trivalent metal ions. Edetate can bind to metals via the four carboxylate and two amine groups, and it forms specially strong complexes with Co(III), Cu(II), Mn(II) and Fe(III). Dimercaprol (BAL, British anti-Lewisite), calcium disodium edetate and penicillamine are the three most common chelating agents used in the treatment of heavy-metal poisoning.
Check Digit Verification of cas no
The CAS Registry Mumber 62-33-9 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 6 and 2 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 62-33:
(4*6)+(3*2)+(2*3)+(1*3)=39
39 % 10 = 9
So 62-33-9 is a valid CAS Registry Number.
