CAS 28307-08-6: L-Threonine,N-[(1,1-dimethylethoxy)carbonyl]-, 4-nitrophenyl ester

Boc-L-threonine 4-nitrophenyl ester is a synthetic amino acid that has been used in peptide synthesis. It is synthesized from the condensation of L-threonine with 4-nitrophenol and bromoacetyl chloride. The two steps of the synthesis are unblocked and side-chain, making it controllable. Boc-L-threonine 4-nitrophenyl ester is also capable of performing the functions of an amino acid, such as deprotection, which is required for peptide synthesis.
