Description
1,1'-Biphenyl, 2,2'-dibromo-5,5'-dinitrois an organic compound that serves as an intermediate in the synthesis of various brominated biphenyls. It is characterized by its chemical structure, which includes a biphenyl core with two bromine atoms and two nitro groups attached to specific positions on the molecule.Uses
Used in Flame Retardant Industry:1,1'-Biphenyl, 2,2'-dibromo-5,5'-dinitrois used as an intermediate in the synthesis of PBB 52 (P216560), which is a related compound of PBB 37 (P215150). These brominated biphenyls are utilized as additives in the flame retardant industry to enhance the fire resistance of materials. The application reason is their ability to slow down the combustion process, making them suitable for incorporation into consumer products such as appliances, electronics, and plastics.
Used in Environmental and Industrial Research:
1,1'-Biphenyl, 2,2'-dibromo-5,5'-dinitroand its related compounds, such as PBB 52 and PBB 37, are also recognized as persistent organic pollutants (POPs). This classification makes them relevant in environmental and industrial research, where they are studied for their potential impact on ecosystems and human health. The application reason is to understand their behavior in the environment, their persistence, and their potential for bioaccumulation in living organisms.
Check Digit Verification of cas no
The CAS Registry Mumber 52026-22-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,2,0,2 and 6 respectively; the second part has 2 digits, 2 and 2 respectively.Calculate Digit Verification of CAS Registry Number 52026-22:
(7*5)+(6*2)+(5*0)+(4*2)+(3*6)+(2*2)+(1*2)=79
79 % 10 = 9
So 52026-22-9 is a valid CAS Registry Number.
