α-Chloro-β-(2,4,5-trichlorophenyl)propionitrile, also known as 2,4,5-T, is a synthetic chemical compound with the molecular formula C9H5Cl4NO. It is a chlorinated nitrile derivative of phenylpropanenitrile, characterized by the presence of three chlorine atoms on the phenyl ring and one chlorine atom on the α-carbon. α-chloro-β-(2,4,5-trichlorophenyl)propionitrile was historically used as a selective herbicide, particularly effective against broadleaf plants and woody species. However, due to its potential health risks and environmental concerns, including its classification as a possible human carcinogen and its persistence in the environment, its use has been banned or restricted in many countries. The compound's chemical structure and properties have been a subject of study in the fields of environmental science and toxicology.

Check Digit Verification of cas no

The CAS Registry Mumber 28029-60-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,0,2 and 9 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 28029-60:
(7*2)+(6*8)+(5*0)+(4*2)+(3*9)+(2*6)+(1*0)=109
109 % 10 = 9
So 28029-60-9 is a valid CAS Registry Number.

Process for the arylation of olefines

-

, (2008/06/13)

A process for arylating an olefinic compound by addition of an aryl group to a double bond of said olefinic compound consisting in diazotizing an arylamine in an aqueous acidic solution comprising a lower alkanoic acid to form a solution of an aryldiazonium salt and reacting said aryldiazonium salt solution with an olefinic compound in an organic solvent in the presence of a catalytically effective amount of a copper halide. The amount of alkanoic acid is about 15 to 37% by volume of the total solvents used. The alkanoic acid is preferably acetic acid and the copper halide cuprous chloride.
