2783-48-4

Phenylphosphonic acid bis(1-methylpropyl) ester, also known as bis(1-methylpropyl) phenylphosphonate, is an organic compound with the chemical formula C??H??O?P. It is a colorless liquid with a density of 1.01 g/cm3 and a boiling point of 300°C. Phenylphosphonic acid bis(1-methylpropyl) ester is a derivative of phenylphosphonic acid, where two 1-methylpropyl (also known as isopropyl) groups are attached to the phosphorus atom. It is used as a flame retardant, plasticizer, and stabilizing agent in various industrial applications, particularly in the production of plastics and resins. Due to its phosphorus content, it exhibits excellent flame-retardant properties, making it a valuable component in the development of fire-resistant materials.

2783-48-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 2783-48-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,7,8 and 3 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 2783-48:
(6*2)+(5*7)+(4*8)+(3*3)+(2*4)+(1*8)=104
104 % 10 = 4
So 2783-48-4 is a valid CAS Registry Number.
