Nα-<4-Nitro-phenoxycarbimidoyl>-benzolsulfonsaeure-hydrazid, also known as Nα-(4-nitrophenoxycarbonyl)benzenesulfonamide hydrazide, is a complex organic compound with the chemical formula C13H12N4O6S. It is a derivative of benzenesulfonamide, featuring a nitrophenoxycarbonyl group attached to the nitrogen atom of the amide. Nα-<4-Nitro-phenoxycarbimidoyl>-benzolsulfonsaeure-hydrazid is often used as a protecting group in peptide synthesis, particularly for the amino group of aspartic acid. It serves to prevent unwanted side reactions during the coupling process, ensuring that the peptide bonds are formed selectively. The nitro group provides a chromophore, allowing for easy monitoring of the deprotection process, which is typically achieved under mild acidic conditions. Nα-<4-Nitro-phenoxycarbimidoyl>-benzolsulfonsaeure-hydrazid is an important tool in the field of organic chemistry and biochemistry, particularly in the synthesis of complex peptides and proteins.

5725-20-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 5725-20-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,7,2 and 5 respectively; the second part has 2 digits, 2 and 0 respectively.Calculate Digit Verification of CAS Registry Number 5725-20:
(6*5)+(5*7)+(4*2)+(3*5)+(2*2)+(1*0)=92
92 % 10 = 2
So 5725-20-2 is a valid CAS Registry Number.
