Uses
Used in Consumer Products and Industrial Applications:
Tris(4-ethylphenyl) phosphate is used as a flame retardant for enhancing the fire safety of various consumer products and industrial materials. It is applied to inhibit the spread of flames and reduce the flammability of plastics, textiles, and polymers, thereby providing a protective layer against fire hazards.
Used in Environmental and Health Research:
Due to concerns about the potential health and environmental impacts of tris(4-ethylphenyl) phosphate, it is also used as a subject of ongoing research. This research aims to understand its persistence in the environment, its bioaccumulation in organisms, and to develop safer alternatives or methods to mitigate its potential risks.
Used in Regulatory Scrutiny:
Tris(4-ethylphenyl) phosphate is a focus in regulatory discussions and assessments to ensure the safety of products that contain it. Regulatory bodies are involved in evaluating its use, setting safety standards, and potentially restricting or banning its application in certain products or industries to protect public health and the environment.
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.
