4-(2-Toluolsulfonyl)-amino-guanidin, also known as 4-tosyl-amino-guanidin or Tosyl-Gly-NH2, is an organic compound with the chemical formula C9H12N2O3S. It is a derivative of guanidine, featuring a tosyl (tosylate) group attached to the 4-position of the guanidine moiety. 4-<2-Toluolsulfonyl>-amino-guanidin is commonly used as a protecting group in peptide synthesis, particularly for the amino group of glycine residues. The tosyl group can be selectively removed under mild conditions, allowing for the deprotection of the amino group and subsequent coupling with other amino acids to form peptides. Its solubility in organic solvents and stability under various reaction conditions make it a valuable tool in the field of organic chemistry and biochemistry.

5725-22-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 5725-22-4 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 2 respectively.Calculate Digit Verification of CAS Registry Number 5725-22:
(6*5)+(5*7)+(4*2)+(3*5)+(2*2)+(1*2)=94
94 % 10 = 4
So 5725-22-4 is a valid CAS Registry Number.
