17269-99-7 Usage
General Description
4-Biphenylol diphenyl phosphate, also known as Diphenyl (4-phenylphenyl) phosphate, is a chemical compound that is frequently used as a component in flame retardants for polymers. It is known for its high thermal stability and effectiveness in preventing the spread of fire. The compound appears as an off-white crystalline powder with a mild odor. It can pose various health risks if swallowed, inhaled, or comes into contact with skin or eyes. It can also cause long term damage to aquatic life when released to the environment. The chemical requires careful handling, storage, and disposal to prevent harm to humans and the environment.
Check Digit Verification of cas no
The CAS Registry Mumber 17269-99-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,2,6 and 9 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 17269-99:
(7*1)+(6*7)+(5*2)+(4*6)+(3*9)+(2*9)+(1*9)=137
137 % 10 = 7
So 17269-99-7 is a valid CAS Registry Number.

METHOD OF PREPARING BIPHENYL-4-YL DIPHENYL PHOSPHATE COMPOSITION
-
Paragraph 0027, (2013/07/19)
Provided is a method of preparing a biphenyl-4-yl diphenyl phosphate composition for use as a flame retardant or a plasticizer for resin, including mixing phosphoryl chloride (POCl3), 4-phenylphenol, and a catalyst, so that first dehydrochlorination occurs; and further adding phenol, so that second dehydrochlorination occurs.
