Uses
Used in Industrial Applications:
2,2',3,4,4',5-HEXACHLOROBIPHENYL was used as a coolant and lubricant in transformers and capacitors for its heat resistance and high dielectric strength.
Used in Chemical Industry:
2,2',3,4,4',5-HEXACHLOROBIPHENYL was utilized as a starting material in the production of various chemicals, such as pesticides and flame retardants, due to its non-flammability and stability.
Used in Plastics and Rubber Industry:
2,2',3,4,4',5-HEXACHLOROBIPHENYL was employed as an additive in the plastics and rubber industry to enhance the products' resistance to heat, light, and electricity.
However, it is important to note that the production and use of PCBs, including 2,2',3,4,4',5-HEXACHLOROBIPHENYL, have been severely restricted or banned in many countries due to their environmental persistence, potential for bioaccumulation, and adverse health effects on humans and wildlife.
Check Digit Verification of cas no
The CAS Registry Mumber 35694-06-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,5,6,9 and 4 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 35694-06:
(7*3)+(6*5)+(5*6)+(4*9)+(3*4)+(2*0)+(1*6)=135
135 % 10 = 5
So 35694-06-5 is a valid CAS Registry Number.

Physical, spectral and chromatographic properties of all 209 individual PCB congeners
Bolgar,et al.
, p. 2687 - 2705 (2007/10/03)
Through the use of two capillary GC columns: 40% octadecyl/ 15% phenyl methyl siloxane and 50% phenyl methyl siloxane, it was possible to separate 201 PCB congeners with only four unresolved pairs. The data compiled in this study for all 209 congeners will aid in the identification of selected individual components of these environmental pollutants. The use of this data also presents the opportunity for the improved quantification of the commercial PCB formulations. -from Authors
