CAS 166737-85-5: H-L-CYS(TRT)-NH2 HCL
Description:H-L-CYS(TRT)-NH2 HCl, with the CAS number 166737-85-5, is a synthetic amino acid derivative that features a cysteine residue protected by a trityl (TRT) group. This compound is characterized by the presence of a thiol (-SH) group, which is typical of cysteine, allowing for potential redox reactions and the formation of disulfide bonds. The hydrochloride (HCl) salt form indicates that the compound is protonated, enhancing its solubility in aqueous solutions. The trityl protection serves to stabilize the thiol group during synthesis or storage, preventing unwanted reactions. This compound is often utilized in peptide synthesis and biochemistry, particularly in the development of peptides that require specific functional groups for biological activity or structural integrity. Its properties, such as solubility, reactivity, and stability, make it a valuable intermediate in the synthesis of more complex molecules in pharmaceutical and biochemical research.
