3820-69-7 Usage
General Description
Tris(4-ethylphenyl) phosphate is an organophosphate flame retardant used in various consumer products and industrial applications. It is a colorless to yellow liquid with a faint aromatic odor and is insoluble in water. Tris(4-ethylphenyl) phosphate is known for its ability to inhibit the spread of flames and reduce the flammability of materials such as plastics, textiles, and polymers. However, concerns have been raised about its potential health and environmental impacts, as studies have shown that it can persist in the environment and bioaccumulate in organisms. As a result, there is ongoing research and regulatory scrutiny on the safety and use of tris(4-ethylphenyl) phosphate in various products.
Check Digit Verification of cas no
The CAS Registry Mumber 3820-69-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,8,2 and 0 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 3820-69:
(6*3)+(5*8)+(4*2)+(3*0)+(2*6)+(1*9)=87
87 % 10 = 7
So 3820-69-7 is a valid CAS Registry Number.

Industrially important triaryl phosphites, traditionally prepared from PCl3, have been synthesized by a diphenyl diselenide-catalyzed one-step procedure involving white phosphorus and phenols, which provides a halogen- and transition metal-free way to these compounds. Subsequent oxidation of triaryl phosphites produces triaryl phosphates and triaryl thiophosphates. Phosphorotrithioates are also prepared efficiently from aromatic thiols and aliphatic thiols.
