General Description
2,3,4,5-Tetrachlorobenzene-1-sulfonyl chloride is a chemical compound with the molecular formula C6HCl4O2S. It is a white to off-white crystalline solid that is insoluble in water. 2,3,4,5-TETRACHLOROBENZENE-1-SULFONYL CHLORIDE is primarily used as an intermediate in the synthesis of pharmaceuticals and agrochemicals. It is also used as a reagent in organic synthesis, specifically in the introduction of the sulfonyl chloride functional group. 2,3,4,5-Tetrachlorobenzene-1-sulfonyl chloride is a highly reactive compound and should be handled with care in a well-ventilated area, as it may release toxic fumes when heated or exposed to air.
Check Digit Verification of cas no
The CAS Registry Mumber 51527-63-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,1,5,2 and 7 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 51527-63:
(7*5)+(6*1)+(5*5)+(4*2)+(3*7)+(2*6)+(1*3)=110
110 % 10 = 0
So 51527-63-0 is a valid CAS Registry Number.

A Convenient Synthesis of High-Purity 1-Chloro-2,6-difluorobenzene
Moore Jr., Robert M.
, p. 921 - 924 (2013/09/05)
A convenient preparation of high-purity 1-chloro-2,6-difluorobenzene has been developed. The key to the isolation of the desired isomer, without contamination of the difficult-to-separate isomer 1-chloro-2,3-difluorobenzene, is the use of sulfonyl chloride to direct fluorine substitution to the ortho and para positions of the aryl ring. Although activation with sulfonyl chloride requires additional reaction steps, the process results in good overall yield and requires only low-cost commodity chemicals. The high-purity 1-chloro-2,6-difluorobenzene is useful as an intermediate for active ingredients in agricultural and pharmaceutical applications.
