2-(N-Benzyloxycarbonyl-L-alanyl)-hydrazinoessigsaeure, also known as Z-Ala-Hyd, is a chemical compound that belongs to the class of hydrazino acids. It is a derivative of L-alanine, an essential amino acid, with a benzyloxycarbonyl (Z) protecting group attached to the nitrogen atom. 2-(N-Benzyloxycarbonyl-L-alanyl)-hydrazinoessigsaeure is widely used in peptide synthesis as a building block, particularly in solid-phase peptide synthesis (SPPS) techniques. The Z group serves as a temporary protecting group for the amino group of the L-alanine residue, preventing unwanted side reactions during the peptide synthesis process. Once the desired peptide sequence is formed, the Z group can be removed under mild acidic conditions, allowing for further reactions or purification steps. Z-Ala-Hyd is a valuable tool in the field of biochemistry and pharmaceutical research, enabling the synthesis of complex peptide structures with high precision and efficiency.
The CAS Registry Mumber 5009-52-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,0,0 and 9 respectively; the second part has 2 digits, 5 and 2 respectively. Calculate Digit Verification of CAS Registry Number 5009-52: (6*5)+(5*0)+(4*0)+(3*9)+(2*5)+(1*2)=69 69 % 10 = 9 So 5009-52-9 is a valid CAS Registry Number.
