938-86-3 Usage
General Description
2,3,4,5-Tetrachloroanisole is a chlorinated derivative of anisole, which is commonly used as a flavoring agent in food products and as an insect repellent in agriculture. It is formed through the chlorination of anisole and is known for its musty, moldy odor. Due to its unpleasant odor, it is considered a contaminant in various materials and can cause tainting of food products and beverages. It is also classified as a potential environmental pollutant due to its persistence and potential to bioaccumulate in the environment. Therefore, it is important to handle and dispose of 2,3,4,5-Tetrachloroanisole carefully in order to minimize its impact on human health and the environment.
Check Digit Verification of cas no
The CAS Registry Mumber 938-86-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,3 and 8 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 938-86:
(5*9)+(4*3)+(3*8)+(2*8)+(1*6)=103
103 % 10 = 3
So 938-86-3 is a valid CAS Registry Number.

Aryne formation from 1-(3′-Carboxyaryl)-3,3-dim ethyl trianzenes
Christopher Buxton,Heaney, Harry
, p. 3929 - 3938 (2007/10/02)
A study of the decomposition of 1-(2′-carboxyphenyl)-3,3-dimethyltriazene and the tetrabromoand tetrachloro- analogues showed that the arenediazonium-2-carboxylates were intermediates in the formation of the corresponding arynes: the 1-(2′-carboxyteirahalophenyl)-3,3-dimethyltriazenes are stable precursors that enable cycloaddition reactions of the tetrahalobenzynes to be carried out in acceptable yields using substrates such as N-methylpyrrole,p-xylene and m-dimethoxybenzene.
