Benzamide, N,N'-thiobis-, also known as 2,2'-Dithiobisbenzamide or Ellman's Reagent, is a chemical compound with the molecular formula C13H10N2O2S2. It is a yellow crystalline solid that is soluble in water and various organic solvents. Benzamide, N,N'-thiobis- is widely used as a reagent in the determination of sulfhydryl groups in proteins and other molecules, as it forms a colored product upon reaction with thiols. The reaction involves the formation of a disulfide bond between the thiol group and the reagent, resulting in a yellow-colored product with a maximum absorbance at 412 nm. This property makes it a valuable tool in biochemistry and analytical chemistry for the detection and quantification of thiols.

6857-06-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 6857-06-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,8,5 and 7 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 6857-06:
(6*6)+(5*8)+(4*5)+(3*7)+(2*0)+(1*6)=123
123 % 10 = 3
So 6857-06-3 is a valid CAS Registry Number.

REACTION OF N,N'-DIAROYLSULFUR DIIMIDES WITH OLEFINS

Barashenkov, G. G.,Derkach, N. Ya.,Levchenko, E. S.,Kalinin, V. N.

, p. 468 - 473 (2007/10/02)

N,N'-Diaroylsulfur diimides react with olefins by a mechanism of the -cycloaddition type with the formation of 2-aryl-4-aroylimino-5,6-dihydro-4,1,3-thiaoxazines.The latter are converted by the action of bases into the N,N'-diaroylamidines of unsatur

DERIVATIVES OF SULFOXYLIC DIAMIDE

Pel'kis, N. P.,Levchenko, E. S.

, p. 1963 - 1967 (2007/10/02)

N,N'-Disubstituted sulfur diimides are reduced by the action of thiophenols to N,N'-disubstituted sulfoxylic diamides R1NHSNHR2.Compounds where R1 = R2 = SO2Ar, COPh enter readily into reaction both with retention and with cleavage of the S-N bond.In reaction with secondary amines and CH acids they are "carriers of sulfur." 2,5-Diaroyl-1,2,5-thiadiazolidine-3,4-diones are formed by the successive action of trimethylchlorosilane and oxalyl chloride on the compounds where R1 = R2 = COPh, COC6H4Cl-p.
