117-71-5 Usage
Uses
Given the hazardous nature of PCB-2,5-diols, their direct use in commercial or industrial applications is highly restricted and generally prohibited due to their toxicity. However, they may be indirectly involved in certain applications, primarily as a subject of study or monitoring in the following contexts:
Used in Environmental Monitoring:
PCB-2,5-diols are used as indicators for environmental contamination, particularly in studies aimed at assessing the presence and impact of persistent organic pollutants in ecosystems. Monitoring the levels of PCB-2,5-diols in the environment helps in understanding the extent of pollution and the need for remediation efforts.
Used in Toxicological Research:
In the field of toxicology, PCB-2,5-diols serve as model compounds for investigating the mechanisms of toxicity and the potential health risks associated with exposure to polychlorinated biphenyls. This research is crucial for developing strategies to mitigate the harmful effects of these pollutants on human health and the environment.
Used in Regulatory Compliance:
PCB-2,5-diols are monitored in industrial processes and waste disposal to ensure compliance with environmental regulations and international agreements that aim to reduce the release of these harmful substances into the environment. This use is essential for enforcing bans and restrictions on the production, use, and disposal of PCBs and related compounds.
Check Digit Verification of cas no
The CAS Registry Mumber 117-71-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,1 and 7 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 117-71:
(5*1)+(4*1)+(3*7)+(2*7)+(1*1)=45
45 % 10 = 5
So 117-71-5 is a valid CAS Registry Number.

Synthesis of amino- and hydroxybiphenyls by radical chain reaction of arenediazonium salts
Wetzel, Alexander,Ehrhardt, Varinia,Heinrich, Markus R.
supporting information; experimental part, p. 9130 - 9133 (2009/02/08)
Radically shortened: In the propagation step of the title reaction, the cyclohexadienyl radical intermediate is oxidized by an arenediazonium ion to give the biaryl product (see scheme) while simultaneously a new aryl radical and nitrogen are formed. (Chemical Equation Presented).
