N-Propionyl-N'-toluol-4-sulfonyl-aethylendiamin, also known as N-Propionyl-N'-tosyl-1,2-ethanediamine, is a chemical compound with the molecular formula C12H18N2O3S. It is a derivative of ethylenediamine, featuring a propionyl group (CH3CH2CO-) attached to one nitrogen atom and a tosyl group (Ts-, which is a toluene-4-sulfonyl group) attached to the other nitrogen atom. N-Propionyl-N'-toluol-4-sulfonyl-aethylendiamin is often used as a protecting group in organic synthesis, particularly in the preparation of peptides and other amines, due to its ability to temporarily block the reactivity of the amine group. The tosyl group can be selectively removed under certain conditions, allowing the amine to regain its reactivity. This property makes N-Propionyl-N'-toluol-4-sulfonyl-aethylendiamin a valuable tool in the synthesis of complex organic molecules.

4554-73-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 4554-73-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,5,5 and 4 respectively; the second part has 2 digits, 7 and 3 respectively.Calculate Digit Verification of CAS Registry Number 4554-73:
(6*4)+(5*5)+(4*5)+(3*4)+(2*7)+(1*3)=98
98 % 10 = 8
So 4554-73-8 is a valid CAS Registry Number.
