Boc-Cys(Bzl)-OH, also known as t-butyloxycarbonyl cysteine benzyl ester, is a valuable building block in chemical synthesis, particularly in peptide synthesis. This compound serves as a protected form of cysteine, an important amino acid with a reactive thiol group. By using Boc-Cys(Bzl)-OH, chemists can selectively protect the thiol group of cysteine during peptide assembly to prevent unwanted side reactions.In peptide synthesis, the Boc (tert-butoxycarbonyl) group on Boc-Cys(Bzl)-OH acts as a protective group for the amino group of cysteine. The benzyl ester group provides additional protection to the carboxylic acid functionality of cysteine. These protective groups can be selectively removed under specific reaction conditions to reveal the reactive thiol group and enable further peptide chain elongation.Overall, Boc-Cys(Bzl)-OH offers chemists a versatile tool for the controlled manipulation of cysteine residues in peptides, enabling the efficient and precise synthesis of complex peptide sequences with desired functionalities.
