4-(4-Benzyloxycarbonylamino-butyrylamino)-thiobutyric acid S-phenyl ester is a complex organic compound with the molecular formula C22H26N2O5S. It is a derivative of thiobutyric acid, featuring a phenyl ester group and a benzyloxycarbonyl-protected butyrylamino moiety. 4-(4-Benzyloxycarbonylamino-butyrylamino)-thiobutyric acid S-phenyl ester is significant in the field of organic chemistry, particularly in peptide synthesis, where it can serve as a building block or a protecting group. The benzyloxycarbonyl (Z) group is a common protecting group used to prevent unwanted side reactions during peptide bond formation, and it can be removed under specific conditions to reveal the free amine group. The S-phenyl ester functionality provides a reactive handle for further chemical modifications or coupling reactions. 4-(4-Benzyloxycarbonylamino-butyrylamino)-thiobutyric acid S-phenyl ester's structure and reactivity make it a valuable intermediate in the synthesis of more complex molecules, such as pharmaceuticals and bioactive peptides.

1656-92-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1656-92-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,5 and 6 respectively; the second part has 2 digits, 9 and 2 respectively.Calculate Digit Verification of CAS Registry Number 1656-92:
(6*1)+(5*6)+(4*5)+(3*6)+(2*9)+(1*2)=94
94 % 10 = 4
So 1656-92-4 is a valid CAS Registry Number.
