Benzeneacetic acid, α-[bis(carboxymethyl)amino]-, also known as N-(α-carboxybenzyl)iminodiacetic acid or CDTA, is a chelating agent with the chemical formula C10H12N2O8. It is a white crystalline powder that is soluble in water and slightly soluble in ethanol. CDTA is widely used in various applications, including water treatment, metal cleaning, and analytical chemistry, due to its ability to form stable complexes with metal ions. It is particularly effective in removing heavy metal ions such as calcium, magnesium, and iron from water, making it useful in softening hard water and preventing scale formation. Additionally, CDTA is employed as a complexing agent in the pharmaceutical and chemical industries, as well as in the analysis of metal ions in environmental and biological samples.
The CAS Registry Mumber 6212-08-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,2,1 and 2 respectively; the second part has 2 digits, 0 and 8 respectively. Calculate Digit Verification of CAS Registry Number 6212-08: (6*6)+(5*2)+(4*1)+(3*2)+(2*0)+(1*8)=64 64 % 10 = 4 So 6212-08-4 is a valid CAS Registry Number.
