S-Trityl-L-cysteine(CAT: R004262) is a chemical compound utilized as a protecting group in peptide synthesis. Its action target involves the protection of the thiol group of L-cysteine during chemical reactions. The mode of action includes adding the trityl (triphenylmethyl) group to the thiol group of L-cysteine, shielding it from unwanted reactions, and enabling specific chemical transformations. Pharmacologically, S-Trityl-L-cysteine itself does not have direct medical applications. Instead, it serves as a valuable tool in organic synthesis, particularly in peptide chemistry, where the trityl protecting group is used to protect and manipulate the reactivity of thiol groups in peptides.
