634-68-4 Usage
Physical properties
1,2,3,4-TETRAIODOBENZENE is a colorless crystalline solid that is highly insoluble in water and has a high melting point.
Uses
It is primarily used as a precursor in the production of various pharmaceuticals and agrochemicals. It is also used in organic synthesis and as a reagent in chemical reactions.
Handling and storage
Due to its highly reactive nature, 1,2,3,4-Tetraiodobenzene should be handled with caution and stored in a cool, dry place away from heat and direct sunlight.
Check Digit Verification of cas no
The CAS Registry Mumber 634-68-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,3 and 4 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 634-68:
(5*6)+(4*3)+(3*4)+(2*6)+(1*8)=74
74 % 10 = 4
So 634-68-4 is a valid CAS Registry Number.

Direct Polyiodination of Benzenesulfonic Acid
Mattern, Daniell Lewis,Chen, Xinhua

Direct aromatic polyiodination of benzenesulfonic acid (using I2 and H5IO6 in H2SO4 at room temperature) was performed to test the possible intermediacy of C6H5SO3H in the corresponding direct polyiodination of benzene to C6H2I4.The major product from C6H5SO3H was 3,4,5-triiodobenzenesulfonic acid (4).In contrast, no 4 was formed in the C6H6 reaction, showing that no significant sulfonation of C6H6 to C6H5SO3H occurred during benzene iodination.Compound 4 itself was shown to be inert under the reaction conditions.A pathway is proposed from C6H5SO3H to the other reaction products (C6I6, C6I5H, two C6I4H2 isomers, and 3,4,5-triiodophenol), which therefore avoids the intermediacy of 4.
