3,3'-Phenylphosphonoyl-di-propionic acid, also known as 3,3'-(Phosphonomethylidyne)dipropylic acid, is a chemical compound with the molecular formula C11H13O7P. It is a white crystalline solid that is soluble in water and slightly soluble in organic solvents. 3,3'-phenylphosphonoyl-di-propionic acid is a derivative of phosphonic acid and is characterized by the presence of a phenyl group connected to two propionic acid groups through a phosphonoyl linker. It is used in various applications, including as a chelating agent, a building block in the synthesis of more complex molecules, and in the production of certain types of polymers. Due to its unique structure, it can form stable complexes with metal ions, making it valuable in industrial processes where metal sequestration is required.
The CAS Registry Mumber 6420-84-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,2 and 0 respectively; the second part has 2 digits, 8 and 4 respectively. Calculate Digit Verification of CAS Registry Number 6420-84: (6*6)+(5*4)+(4*2)+(3*0)+(2*8)+(1*4)=84 84 % 10 = 4 So 6420-84-4 is a valid CAS Registry Number.
