N,N,N′,N′-p-xylylenediamine tetraacetic acid, also known as PXT, is a chelating agent that belongs to the family of ethylenediaminetetraacetic acid (EDTA) derivatives. It is a white crystalline powder with the chemical formula C18H24N2O8. PXT is widely used in various applications, including water treatment, metal finishing, and pharmaceuticals, due to its ability to form stable complexes with metal ions. This property makes it effective in removing heavy metals from water and soil, as well as in preventing metal-induced oxidation in industrial processes. Additionally, PXT has been studied for its potential therapeutic uses, such as in the treatment of certain metal poisoning and as a contrast agent in medical imaging. Its chemical structure, which includes two ethylenediamine chains connected by a para-xylylenediamine bridge, allows for the formation of multiple coordination bonds with metal ions, enhancing its chelating efficiency.
The CAS Registry Mumber 6411-02-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,1 and 1 respectively; the second part has 2 digits, 0 and 2 respectively. Calculate Digit Verification of CAS Registry Number 6411-02: (6*6)+(5*4)+(4*1)+(3*1)+(2*0)+(1*2)=65 65 % 10 = 5 So 6411-02-5 is a valid CAS Registry Number.
