7357-41-7 Usage

Uses

Diphenyl Sulfone-3,3''-disulfonyl Chloride is the derivative of 4,4’-Dichlorodiphenyl Sulfone (D434165), which is an antibacterial used in the treatment of dermatitis herpetiformis.

Check Digit Verification of cas no

The CAS Registry Mumber 7357-41-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,3,5 and 7 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 7357-41:
(6*7)+(5*3)+(4*5)+(3*7)+(2*4)+(1*1)=107
107 % 10 = 7
So 7357-41-7 is a valid CAS Registry Number.

Synthesis of biologically active of some novel sulphonamides

Zaky,Mohamed,Nail,Kandil

, p. 321 - 331 (2007/10/03)

CONTROLLED chlorosulponation of diphenylsulphone (1), thiaxanthone (2) and benzophenone (3) with chlorosulphonic acid yielded diphenylsulphone-3,3′- disulphonyl-chloride (4a), thiaxanthone-3,3′- disulphonylchloride (5) and benzophenone -3,3′-di

CHLOROSULFONATION OF SOME DIPHENYL DERIVATIVES

Cremlyn, Richard,Montgomery, Stephen,Ng, Yew,Simpson, David

, p. 341 - 352 (2007/10/02)

Benzophenone (1), diphenyl sulfone, and 4-nitro-2'-chloro- and 4-nitro-2',6'-dichlorophenyl ethers (23,24) have been chlorosulfonated.The direct yield of benzophenone-3,3'-disulfonyl chloride (2) was low, the majority of product was the disulfonic acid.Diphenyl sulfone (11) with a large amount of chlorosulfonic acid (8 mols) at 140 deg gave the 3,3'-disulfonyl chloride (12).With less reagent (6 mols) at 90 deg a mixture of the 3-sulfonyl chloride (21) and diphenyl sulfone was formed.Subsequent reaction with sodium azide gave the 3-sulfonyl azide (22).The diphenyl ether sulfonyl chlorides (25,26) were very susceptible to hydrolysis, especially (26) which probably accounts for the low yield obtained (31percent).The various sulfonyl chlorides were characterized as amides, azides, hydrazides and hydrazones (Tables I-III) and their i.r., n.m.r., and mass spectral data are included.
