5216-26-2 Usage

General Description

(E)-4,4',α,β-Tetrachlorostilbene is a highly toxic and persistent chemical compound that belongs to the group of stilbene derivatives. It is known for its ability to bioaccumulate in living organisms and the environment. Its structure consists of a central stilbene backbone with four chlorine atoms attached to alternating carbon atoms. (E)-4,4',α,β-Tetrachlorostilbene is a potential environmental contaminant and is of concern due to its potential negative impact on human health and the environment. It may have harmful effects on the liver, reproductive system, and immune system, and has been found to be a potent endocrine disruptor in animal studies. Due to its toxic nature, it is important to limit its production, use, and release into the environment and to find alternative, safer substances to replace it.

Check Digit Verification of cas no

The CAS Registry Mumber 5216-26-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,2,1 and 6 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 5216-26:
(6*5)+(5*2)+(4*1)+(3*6)+(2*2)+(1*6)=72
72 % 10 = 2
So 5216-26-2 is a valid CAS Registry Number.

CONVERSION OF DISILANES TO FUNCTIONAL MONOSILANES. XIII. THE PALLADIUM CATALYZED REDUCTIVE COUPLING OF BENZYLIDENE DICHLORIDES AND BENZYLIDYNE TRICHLORIDES USING DISILANES AS REDUCING AGENTS.

Matsumoto,Arai,Takahashi,Ashizawa,Nakano,Nagai

, p. 3009 - 3014 (2007/10/02)

The reaction of benzylidene dichlorides or benzylidene trichlorides with 1,2-dichloro-1,1,2,2-tetramethyl-disilane or hexamethyldisilane proceeded smoothly in the presence of a catalytic amount of Pd(PPh//3)//4 to give (E)-stilbenes or (E)- and (Z)- alpha beta -dichlorostilbenes in high yields, respectively. Also, in the presence of the palladium (0) catalyst, alpha , alpha -dichlorobenzyltrimethylsilanes reacted with hexamethyldisilane yielding (E)- alpha , beta -bis(trimethylsilyl)stilbenes in quantitative yield.
