2,5-Dichloro-4'-nitrobiphenyl is a chemical compound characterized by the presence of two chlorine atoms at the 2nd and 5th positions on the biphenyl ring and a nitro group at the 4' position. This organic compound is part of a larger group known as polychlorinated biphenyls (PCBs), which are a class of chemicals that have been widely used in various industrial applications due to their heat resistance and electrical insulating properties. However, due to their persistence in the environment and potential health risks, including endocrine disruption and carcinogenicity, the production and use of many PCBs, including 2,5-Dichloro-4'-nitrobiphenyl, have been restricted or banned in several countries. The compound's specific structure and properties make it a subject of interest in environmental and health studies, as it can accumulate in the food chain and pose risks to both wildlife and human health.

2765-22-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 2765-22-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,7,6 and 5 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 2765-22:
(6*2)+(5*7)+(4*6)+(3*5)+(2*2)+(1*2)=92
92 % 10 = 2
So 2765-22-2 is a valid CAS Registry Number.

Reactivity of C-H bonds of polychlorobenzenes for palladium-catalysed direct arylations with aryl bromides

Zhao, Liqin,Yan, Tao,Bruneau, Christian,Doucet, Henri

, p. 352 - 360 (2014/02/14)

The reactivity of polychlorobenzenes vs. polyfluorobenzenes for palladium-catalysed direct arylation was studied. The PdCl(C3H 5)(dppb)/KOAc system was found to promote the direct arylation of some polychlorobenzenes with aryl bromid

Nucleophilic substitutions and radical reactions of phenylazocarboxylates

Jasch, Hannelore,Hoefling, Sarah B.,Heinrich, Markus R.

experimental part, p. 1520 - 1532 (2012/03/11)

tert-Butyl phenylazocarboxylates are versatile building blocks for synthetic organic chemistry. Nucleophilic substitutions of the benzene ring proceed with aromatic amines and alcohols under mild conditions. The attack of aliphatic amines may be directed to the aromatic core as well as to the carbonyl unit leading to azocarboxamides. The benzene ring can further be modified through radical reactions, in which the tert-butyloxycarbonylazo group enables the generation of aryl radicals at either elevated temperatures or under acidic conditions. Radical reactions include oxygenation, halogenation, carbohalogenation, carbohydroxylation, and aryl-aryl coupling.
