Bis-N,N'-(2-carboxy-3-phenyl-propionyl)-hexamethylendiamin, also known as Bis-HMPA, is a complex organic compound with the chemical formula C26H34N2O4. It is a derivative of hexamethylenediamine, featuring two 2-carboxy-3-phenyl-propionyl groups attached to the nitrogen atoms. This white crystalline solid is soluble in water and various organic solvents, and it is commonly used as a chelating agent in analytical chemistry, particularly for the determination of metal ions. Bis-HMPA is also employed in the synthesis of metal complexes and as a ligand in coordination chemistry, due to its ability to form stable complexes with a wide range of metal ions. Its applications extend to areas such as environmental analysis, pharmaceuticals, and materials science, where it plays a role in enhancing the selectivity and sensitivity of certain analytical methods.
The CAS Registry Mumber 5725-71-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,7,2 and 5 respectively; the second part has 2 digits, 7 and 1 respectively. Calculate Digit Verification of CAS Registry Number 5725-71: (6*5)+(5*7)+(4*2)+(3*5)+(2*7)+(1*1)=103 103 % 10 = 3 So 5725-71-3 is a valid CAS Registry Number.
