34732-09-7 Usage
General Description
2,3,4-Trichlorobenzenesulfonyl chloride is a chemical compound used as an intermediate in the synthesis of pharmaceuticals and agrochemicals. It is a highly reactive and corrosive compound that is used in the production of sulfonamide antibiotics, sulfonylurea herbicides, and other organic compounds. It reacts violently with water and must be handled with care due to its toxic and irritant properties. It is typically used in a controlled laboratory setting under strict safety precautions to avoid exposure and accidents. 2,3,4-TRICHLOROBENZENESULFONYL CHLORIDE is also used as a building block in the synthesis of dyes and other organic compounds.
Check Digit Verification of cas no
The CAS Registry Mumber 34732-09-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,7,3 and 2 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 34732-09:
(7*3)+(6*4)+(5*7)+(4*3)+(3*2)+(2*0)+(1*9)=107
107 % 10 = 7
So 34732-09-7 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.
