Tris(2-phenoxyethyl) phosphite, also known as TPP or TPEP, is a colorless, viscous liquid with the chemical formula C24H27O3P. It is a phosphorus-based flame retardant and plasticizer, commonly used in the production of polyvinyl chloride (PVC) and other polymers to enhance their fire resistance and flexibility. TPP is known for its high thermal stability, low volatility, and excellent compatibility with various polymers, making it a preferred additive in the plastics industry. It is also used as a stabilizer in the production of polyurethane foams and as an antioxidant in lubricants. Due to its effectiveness in improving the flame retardancy of materials, tris(2-phenoxyethyl) phosphite plays a crucial role in ensuring safety in various applications, from construction to electronics.

4486-47-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4486-47-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,4,8 and 6 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 4486-47:
(6*4)+(5*4)+(4*8)+(3*6)+(2*4)+(1*7)=109
109 % 10 = 9
So 4486-47-9 is a valid CAS Registry Number.
