N-Trifluoracetyl-glycyl-S-benzyl-L-cystein-methylester is a complex organic compound with the molecular formula C15H16F3NO4S. It is a derivative of the amino acid cysteine, featuring a trifluoroacetyl group at the nitrogen, a glycyl group (glycine) attached to the alpha carbon, a benzyl group at the sulfur, and a methyl ester at the carboxylic acid end. N-Trifluoracetyl-glycyl-S-benzyl-L-cystein-methylester is often used in peptide synthesis as a protecting group for cysteine residues, which helps prevent unwanted side reactions during the assembly of peptide chains. The trifluoroacetyl group provides a stable and easily removable protection, while the benzyl group protects the thiol group of cysteine, and the methyl ester is a common protecting group for the carboxylic acid. The compound plays a crucial role in the synthesis of peptides and proteins, particularly in the pharmaceutical and biotechnology industries, where it aids in the controlled formation of disulfide bonds and the stabilization of peptide structures.

856-43-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 856-43-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,5 and 6 respectively; the second part has 2 digits, 4 and 3 respectively.Calculate Digit Verification of CAS Registry Number 856-43:
(5*8)+(4*5)+(3*6)+(2*4)+(1*3)=89
89 % 10 = 9
So 856-43-9 is a valid CAS Registry Number.
