1,2-bis[isopropoxy(phenyl)phosphoryl]ethane, also known as bis(isopropoxyphenyl)phosphine oxide or BIPPPO, is a phosphorus-containing organic compound with the chemical formula C20H25O4P. It is a colorless to pale yellow liquid and is used as a flame retardant, plasticizer, and stabilizing agent in various industrial applications, particularly in the production of polyvinyl chloride (PVC) and other polymers. BIPPPO is known for its effectiveness in improving the thermal stability and flame resistance of materials, while also offering good compatibility with the polymer matrix. It is also used in the synthesis of other organophosphorus compounds and as a ligand in coordination chemistry. Due to its potential health and environmental concerns, proper handling and disposal procedures should be followed when working with this chemical.

2240-53-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 2240-53-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,2,4 and 0 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 2240-53:
(6*2)+(5*2)+(4*4)+(3*0)+(2*5)+(1*3)=51
51 % 10 = 1
So 2240-53-1 is a valid CAS Registry Number.
