7244-02-2 Usage
General Description
Ethylene dithio diacetic acid, also known as EDTA, is a versatile chelating agent and a widely used chemical in various industrial and commercial applications. It is a colorless, water-soluble solid compound with a molecular formula C6H10O4S2 and is commonly used in the production of soaps, detergents, and water treatment products. EDTA is highly effective in binding to metal ions, making it a popular additive in metal cleaning and extraction processes. It is also utilized in the pharmaceutical and cosmetic industries for its ability to improve product stability and shelf life. Additionally, EDTA is employed in analytical chemistry as a complexing agent to accurately measure metal ions in various samples.
Check Digit Verification of cas no
The CAS Registry Mumber 7244-02-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,2,4 and 4 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 7244-02:
(6*7)+(5*2)+(4*4)+(3*4)+(2*0)+(1*2)=82
82 % 10 = 2
So 7244-02-2 is a valid CAS Registry Number.

A Convenient Synthesis of the Symmetrical Bis-Sulfides Under Phase Transfer Conditions
Jian-Hua, Wang,Zhen, Zhang,Yong-Lai, Feng
, p. 373 - 377 (2007/10/02)
Phase transfer catalysis has been found to be effective for the preparation of symmetrical bis-sulfides (4) in high yields by a one-pot procedure which consists of generating the thiolate ions from S-alkylisothiouronium salts (2) and then reacting with alkyl halides (3).
Complexes of macrocyclic compounds

, (2008/06/13)
Novel macrocyclic (monocyclic and bicyclic) compounds having nitrogen bridgehead atoms and having in the hydrocarbon bridging chains at least two additional hetero atoms selected from the group consisting of sulfur, oxygen, and nitrogen, when admixed with a compatible cation-donor compound form stable cation-containing macrocyclic complexes which, in turn, can be conveniently dissociated by addition of acid or a quaternizing agent. The novel macrocyclics are valuable for use in the same way and for the same purposes as chelating agents.
