6936-40-9 Usage
General Description
2,3,5,6-Tetrachloroanisole is a chemical compound that is a derivative of anisole and contains four chlorine atoms. It is most commonly known for its musty, moldy odor, which makes it an off-flavor in wines and other food products. It is produced through the chlorination of anisole and can also be found in pesticides and fungicides. It is considered to be a potential environmental contaminant and is known to have a negative impact on the taste and aroma of affected products. Additionally, 2,3,5,6-Tetrachloroanisole is not considered to be a highly toxic compound, but exposure to high levels may cause irritation of the respiratory tract and skin.
Check Digit Verification of cas no
The CAS Registry Mumber 6936-40-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,9,3 and 6 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 6936-40:
(6*6)+(5*9)+(4*3)+(3*6)+(2*4)+(1*0)=119
119 % 10 = 9
So 6936-40-9 is a valid CAS Registry Number.

Activation of chlorine and fluorine by a phenylazo group towards nucleophilic aromatic substitution. Regioselective preparation of polysubstituted anilines
Fryszkowska, Anna,Tilford, Robert W.,Guo, Fengli,Kaszynski, Piotr
, p. 2327 - 2333 (2007/10/03)
A phenylazo group was used for selective activation of ortho fluorine and chlorine atoms towards nucleophilic aromatic substitution with the propanethiolate anion. This enabled a regioselective synthesis of three substituted 4-alkoxyanilines. The regioselectivity of substitution was confirmed by comparison of experimental NMR chemical shifts with empirically predicted values. The observed reactivity of the substrates is discussed in the context of the substituent effect.
