73575-53-8 Usage
General Description
2,3'',4,5-Tetrachlorobiphenyl is a type of polychlorinated biphenyl (PCB) compound that consists of four chlorine atoms attached to a biphenyl molecule. It is a persistent organic pollutant that was used in various industrial and commercial applications, including electrical equipment and hydraulic fluids. Due to its high thermal stability and chemical inertness, 2,3'',4,5-tetrachlorobiphenyl has been found to persist in the environment and accumulate in the fatty tissues of organisms. It is also known for its toxic effects on human health and the environment, and has been linked to a range of detrimental impacts, including developmental and neurological disorders, as well as reproductive and immune system problems. The production and use of 2,3'',4,5-tetrachlorobiphenyl has been banned or heavily restricted in many countries, but it continues to pose a threat due to its long-term persistence and bioaccumulation in the environment.
Check Digit Verification of cas no
The CAS Registry Mumber 73575-53-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,5,7 and 5 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 73575-53:
(7*7)+(6*3)+(5*5)+(4*7)+(3*5)+(2*5)+(1*3)=148
148 % 10 = 8
So 73575-53-8 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
