Benzyloxycarbonyl-DL-α-phenyl-alanin-tert-butylester, also known as Z-DL-Phe-OtBu, is a complex organic compound that serves as a protected amino acid derivative. It is widely used in peptide synthesis, particularly in solid-phase peptide synthesis (SPPS), where it acts as a building block for the formation of peptide bonds. The compound features a benzyloxycarbonyl (Z) group, which is a protecting group for the amino group, and a tert-butyl (tBu) group, which protects the carboxylic acid group. These protecting groups are crucial for preventing unwanted side reactions during the peptide synthesis process. Once the peptide chain is complete, the protecting groups can be removed to yield the desired peptide. Z-DL-Phe-OtBu is a racemic mixture, containing both the D and L isomers of phenylalanine, which are the two enantiomers of the amino acid. Benzyloxycarbonyl-DL-α-phenyl-alanin-tert-butylester is essential in the pharmaceutical and biotechnology industries for the development of new drugs and therapeutics.

4507-45-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 4507-45-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,5,0 and 7 respectively; the second part has 2 digits, 4 and 5 respectively.Calculate Digit Verification of CAS Registry Number 4507-45:
(6*4)+(5*5)+(4*0)+(3*7)+(2*4)+(1*5)=83
83 % 10 = 3
So 4507-45-3 is a valid CAS Registry Number.
