12264-18-5 Usage
General Description
ETHYLENEDIAMINETETRAACETIC ACID DICALCIUM SALT is a chemical compound that is commonly used as a chelating agent and sequestrant, and also as a stabilizer and preservative in various industrial and household products. It is a white, odorless powder that is highly soluble in water and has a pH value of around 6.5-7.5. The compound is known for its ability to bind to metal ions, such as calcium and magnesium, and prevent them from reacting with other substances or forming unwanted deposits. It is commonly used in the food and beverage industry to prevent rancidity and discoloration, and in the pharmaceutical and cosmetic industry as a stabilizer and preservative. Additionally, it is used in the production of cleaning and personal care products to improve their effectiveness and stability. Overall, ETHYLENEDIAMINETETRAACETIC ACID DICALCIUM SALT plays a crucial role in a wide range of applications due to its chelating and sequestering properties.
Check Digit Verification of cas no
The CAS Registry Mumber 12264-18-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,2,6 and 4 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 12264-18:
(7*1)+(6*2)+(5*2)+(4*6)+(3*4)+(2*1)+(1*8)=75
75 % 10 = 5
So 12264-18-5 is a valid CAS Registry Number.

Dynamic Features of the Ethylenediaminetetraacetate Complexes of Ca, Sr, Ba, and Co(II) in Aqueous Solutions Studied by the Ultrasonic Absorption Method
Harada, Shoji,Funaki, Yoshinori,Yasunaga, Tatsuya
, p. 136 - 139 (1980)
Ultrasonic absorption was measured in aqueous solutions of ethylenediaminetetraacetate(EDTA) complexes of Ca, Sr, Ba, and Co(II) (1:1 complex).The absorption was ascribed to the configuration change reaction of the complex, i.e., pentacoordinated structure hexacoordinated structure (kf, kb).Rate constants kf,kb and the volume change of the reaction ΔV were obtained.The rate constant was discussed in relation to the coordinated water substitution rate constants of the metal ions with use of a step-by-step mechanism.Supplementary work is reported for the Co(II) complex solutions of EDTA-related ligands.
