13291-61-7 Usage
Description
1,2-Cyclohexylenedinitrilotetraacetic acid, also known as CDTA, is an organic compound that exists as a white powder. It is a derivative of cyclohexane with two nitrile groups and four carboxylic acid groups, which contribute to its chelating properties.
Uses
Used in Environmental Remediation:
1,2-Cyclohexylenedinitrilotetraacetic acid is used as a chelating agent for the phytoextraction of nickel (Ni) from contaminated soil. Its ability to form stable complexes with metal ions aids in the process of removing harmful metals from the environment, thus contributing to soil remediation and restoration efforts.
(Note: The provided materials do not mention any other specific applications for 1,2-Cyclohexylenedinitrilotetraacetic acid. If there are additional uses in different industries, they would need to be provided in the materials for inclusion in the response.)
Flammability and Explosibility

Purification Methods
Dissolve CDTA in aqueous NaOH as its disodium salt, then precipitate it by adding HCl. The free acid is filtered off and boiled with distilled water to remove traces of HCl [Bond & Jones Trans Faraday Soc 55 1310 1959]. Recrystallise it from water and dry it in vacuo.[Beilstein 13 III 10.]
Check Digit Verification of cas no
The CAS Registry Mumber 13291-61-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,2,9 and 1 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 13291-61:
(7*1)+(6*3)+(5*2)+(4*9)+(3*1)+(2*6)+(1*1)=87
87 % 10 = 7
So 13291-61-7 is a valid CAS Registry Number.
