p-Nitrobenzenesulfonyl peroxide (PNBS) is an organic compound with the chemical formula C12H10N2O6S. It is a derivative of benzene, where a nitro group (-NO2) is attached to the para position, and a sulfonyl peroxide group (-SO2OOH) is attached to the ortho position. PNBS is a pale yellow solid that is soluble in organic solvents such as dichloromethane and acetone. It is commonly used as a selective reagent for the detection and quantification of thiols, particularly in the presence of other functional groups. The reaction between PNBS and thiols results in the formation of a colored product, which can be used for spectrophotometric analysis. Due to its reactivity and specificity, PNBS is widely employed in various fields, including biochemistry, organic synthesis, and analytical chemistry.

5997-78-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 5997-78-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,9,9 and 7 respectively; the second part has 2 digits, 7 and 8 respectively.Calculate Digit Verification of CAS Registry Number 5997-78:
(6*5)+(5*9)+(4*9)+(3*7)+(2*7)+(1*8)=154
154 % 10 = 4
So 5997-78-4 is a valid CAS Registry Number.
